When I am trying to subscribe to livejournal RSS feed (by adding /rss to the url), I see "verifying the RSS feed..." status in the Manage Subscriptions dialog forever and the RSS feed never shows up in the main TB window. After half an hour I simply close the Manage Subscriptions window w/o any results. Also note that I don't see any HTTP requests in ethereal.

Reproducible: Always

Steps to Reproduce:
1. Right click on "News & Blogs", choose "Manage Subscriptions..."
2. Click "Add" button
3. Put any livejournal rss feed uri in "Feed URL" text box.
4. Observe "verifying the RSS feed..." in the status forever
Actual Results:  
"Verifying the RSS feed..." in the status statys forever, feed is not subscribed.

Expected Results:  
Feed is subscribed.

TB version -> 1.5 rc3

UPDATE: I used RSS feed before upgrading to 1.5 RC3 and it seems to be the reason for my problems. After I manually removed everything in "News & Blogs" folder in my profile the problem went away.

Which build were you using *before* installing the 1111 build -- another 1.5, 
or something from the 1.0 branch?  (NB: I don't think there has been an actual 1.5rc3 release yet, or even rc2 -- just nightlies.)

Could you provide a URL to the feed, please?

I was using 1.0.x build before (sorry, exact version information was lost after upgrade) and upgraded to version 1.5 (20051111) which I downloaded from here ftp://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/1.5rc3-candidates. 

This problem did occur with every single livejournal rss feed I've tried. For example, http://www.livejournal.com/users/tightlink/data/rss

The feed referenced validates without a problem, at feedvalidator.org.

I tried subscribing, using 1.5rc1 and 1.6a1-1201, and had problems.  When I 
add the feed, it is apparently parsed in its entirety (the progress bar moves smoothly across), then the subscribe dialog hangs; the JavaScript console 
shows two errors:
=====
Error: not well-formed
Source File: file:///M:/Application%20Data/Thunderbird/Feeds/feeditems.rdf
Line: 1

Error: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIRDFService.GetDataSourceBlocking]"  nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)"  location: "JS frame :: chrome://messenger-newsblog/content/utils.js :: getItemsDS :: line 222"  data: no]
Source File: chrome://messenger-newsblog/content/utils.js
Line: 222
=====
But note, my system is possibly broken (see bug 313422 comment 32 et seq).

xref bug 264482 comment 12, and bug 313422 comment 32.
Note that the LiveJournal feed is 2.0, not 0.9 like bug 313422 is about.

Hmm. Just tried it on a fresh trunk build and had no issues.

The exception in utils.js occurs when the code looks for the RDF files:

line222> server.QueryInterface(Components.interfaces.nsIRssIncomingServer);

OK, as I just noted in bug 313422, I create a brand new profile and was able to subscribe without problems, using 1.6a1-1201.  I then wiped out the RSS account (including deleting the files after closing TB) from my regular profile, restarted TB, created a new RSS account, and successfully subscribed to this feed, with both 1.5rc1 and 1.6a1-1201.

So, reporter may have the same problems with his existing profile as I had with mine, whatever those problems may be.

Alexsey Sanin, when you attempt to subscribe, do you see the same error as in comment 5?

Before you wipe out your RSS account, please make a backup of the files in the RSS account's directory (like I *should* have done), in case Robert would like to have a sample broken account to test with.

1) Yes, if I open the Java Script console I see the same error.
2) As I wrote before, it happens only with "old" rss profile. If I delete everything from "News & Blogs" folder, the error goes away and I can subscrbe w/o any problem.
