In order to get categories for RSS feeds, I created 3 different RSS accounts. In this configuration, 2 annoying problems appears :
- many times the entries are re-download, and so appears twice in feeds
- no support for the "show the article summary" option (always show the web page)
First I was thinking this problem was maybe caused by the antivirus software (Norton Antivirus 184.108.40.2068), but disabling it didn't worked. So I export all the accounts in OPML files, delete them, recreate one account and import the OPML files. Since then, everything works as expected.
Steps to Reproduce:
1. Create one RSS account
2. Add RSS feeds to it (directly in the acount settings windows or in 2 steps, closing the account settings windows then open the manage subscription link in the account context menu)
3. repeat steps 1 and 2 to create 2 or more RSS accounts
4. close Thunderbird, open it : the RSS fees articles are retrieved. Mark them as read
5. close Thunderbird, open it : for some RSS feeds certains articles already presents in thunderbird are downloaded again
- Duplicates entry in RSS feeds
- Always display the article web page instead of the summary whereas the appropriate option is checked or not

I am having this exact same problem. I have multiple RSS feeds in one account and occassionally I get all the previously read entries duplicated and marked as new. I think it primarily happens after I add/remove feeds.
This is happening in 220.127.116.11 and also in earlier versions.
I'd actually written up a bug report about this same problem before finding this one, so confirming. (I'd concentrated my report on the multiple messages problem, although I also see problems with "Show the article summary instead of loading the Web page".) I'd also note that the multiple messages problem seems to show up in situations where we're processing feeds in different accounts at the same time. The report I'd written was the following:
Thunderbird feed downloading tends to get confused about what feed items are new and what have been already downloaded when it's downloading feeds in two *accounts* simultaneously. I've noticed this problem quite a bit in various situations while using both Thunderbird 1.5.0.x and Thunderbird 2.0b1 -- I have my RSS Feeds grouped into 5 separate accounts (with one folder per feed).
My suspicion is that the problem is related to downloading feeds in multiple accounts at the same time. When I explicitly get new messages on the accounts so they're not downloading at the same time, I don't see the problem.
The steps to reproduce below are the most reliable way I've found to reproduce the problem. (I'd been testing most of the time with feeds behind HTTP auth, without saving the passwords, since I thought that would make it even more reliable. However, it seems to be reliable even without that.) These steps show the problem 100% of the time for me, whereas in general the problem is rather intermittent (and annoying), since I'm not always downloading messages for multiple accounts at the same time.
Steps to reproduce:
1. Start Thunderbird 2.0 beta 1 on a clean profile
2. when the account manager comes up, create a RSS News & Blogs
account (accept all defaults)
3. File -> New -> Account, and create a *second* RSS News & Blogs
account. (Call this one something else.)
4. Right click on each accounts in the folder pane, select
"Properties", and change the "100" (check for new messages every) to
5. Right click on the first account in the folder pane, click
subscribe, click add, and add a feed.
6. Do the same in the other account, for another feed.
7. Quit thunderbird
8. Start thunderbird again.
9. click on the one folder in each account in the minute before
thunderbird checks for messages (because check for new messages at
startup doesn't actually work, so you have to wait for the one
minute delay), and press Shift-C to mark all the messages in the
account as read so it's easy to see what gets newly downloaded.
10. wait 1 minute for Thunderbird to check for new messages (in both
Actual results: All the articles currently in the feed that was
downloaded second (I think it's the one downloaded second based on my
testing with HTTP auth -- in which case it's the one whose auth dialog
comes up second) get re-downloaded, even though you've already
downloaded them once, so that you have duplicate email (one read thanks
to the mark-all-read in step 9), and one unread).
Expected results: No duplicate messages created by checking feeds.

So when looking at the feeds.rdf and feeditems.rdf files in the accounts in my profile, I've noticed a lot of entries in those files for feeds that belong to other accounts. Then, looking around the code, I found this problem. I haven't yet had a chance to test whether it fixes the problems -- and if so, I'm not sure what it would do to existing profiles with multiple accounts.
I'll try to test this today or tomorrow...

This does fix the problem (tested in a 1.8 branch build, using the steps in comment 5).
I haven't tried it on my existing profile yet -- I'm not sure how it will react to the already-corrupted RDF files -- whether things will be worse, the same, or better. But I think we probably do want to fix this either way.

thanks a lot David.
Checked in to trunk and MOZILLA_1_8_BRANCH.
This was not fixed in Beta 2 as claimed. I am experiencing this behaviour in Beta 2 build 20070116.
Okay, maybe this exact bug was fixed, as I am only using a single RSS account, but with subfolders. However, duplicate entries do still show up - am searching for the correct bug to vote for. My bad.
I still have this problem with Thunderbird 18.104.22.168 : Duplicate entries still show up for some RSS feed, for exemple this one : http://ditwww.epfl.ch/EPFLTV/RSS/rss_lastentries_f.xml
Could it be a server problem now ?
There are certainly other reasons for duplicate messages; it's better to track them in separate bugs.
