I'm not able to delete both at all. It will be back after restart if I remove one and rename the other and then remove it as well. Sometimes I even cannot rename the folder. So I hope you're able to reproduce it. Reproducible: Always Steps to Reproduce: 1. Add http://support.asus.de/rss/RssFeeds.aspx?product=1&model=M4A79XTD%20EVO&SLanguage=en-us as news feed 2. See two new news folders with the same name (if not restart tb) 3. Try to delete one or even both Actual Results: It adds folders with the same name twice. You're not able to delete one or even both of them. Expected Results: Only one folder should be added. I should be able to remove it as well.
I can't reproduce the dual folder issue with Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:184.108.40.206pre) Gecko/20100221 Lanikai/3.1b1pre. Have you tried safe mode? (see https://support.mozillamessaging.com/en-US/kb/Safe+Mode for more information)
It does appear twice after a restart of Thunderbird.
Even in safe-mode I'm only able to delete both feeds but only one of these folders. When trying to remove the second folder I just get "A folder with that name already exists. Please enter a different name.".. but even that doesn't work as expected.
My could you look into this one ?
(In reply to comment #4) > My could you look into this one ? Myk would you have bandwidth to look into this one ?
I don't have too much bandwidth, but I took a look this evening, and I found that subscribing to the feed creates three files in the Mail/News & Blogs/ subdirectory of the profile directory: ASUSTek RSS [Motherboard] [M4A79XTD EVO] [en-us]82439776 ASUSTek RSS [Motherboard] [M4A79XTD EVO] [en-usd77a79f2 ASUSTek RSS [Motherboard] [M4A79XTD EVO] [en-usd77a79f2.msf The feeds.rdf file specifies the fz:destFolder for the feed as: <fz:destFolder RDF:resource="mailbox://nobody@News%20%26%20Blogs/ASUSTek%20RSS%20%5BMotherboard%5D%20%5BM4A79XTD%20EVO%5D%20%5Ben-us%5D82439776"/> However, the file ending in "d77a79f2" is the one to which feed messages have been added (and the one being indexed via a Mork database). I suspect that some code creates the file ending in "82439776" when one subscribes to the feed, then some other code creates "d77a79f2" when it downloads feed messages. I haven't been able to figure out where those respective code chunks live, however.
Thanks for the analysis.
What produces them should be NS_MsgHashIfNecessary - http://mxr.mozilla.org/comm-central/source/mailnews/base/util/nsMsgUtils.cpp#99 - but i doubt that helps much.
the reason is that the feed title ends in empty space. feeditem titles that end in empty space also cause trouble if just the right length. trim() is a friend here..
