User-Agent: Opera/7.50 (X11; Linux i686; U) [en] Build Identifier: I had a folder named "Inne" with some messages and subfolders in it. Then I tried to create a subfolder named "/.". Reproducible: Didn't try Steps to Reproduce: 1. Have a folder with subfolders and messages 2. Create a subfolder named "/." 3. Enjoy. Actual Results: It resulted in Thunderbird freezing (eating up 100% of CPU cycles). After restart I have "Inne" renamed to "/.", one new folder named "80a829e8". Changing name from "/." back to "Inne" fails with "The folder cound not be renamed. Perhaps the folder is being reparsed, or the name is not a valid folder name". Expected Results: Thunderbird should either use a clever "trick" to create such folder or deny it. I use version 0.6 (20040608) from unstable branch of Gentoo Linux.

I run win98 with Thunderbird 0.7.2 with build 20040707 and I also get this error with creating a folder starting with "/" and anything else.

Oh, SlashDot is one of the worst folder name for Thunderbird and Mozilla Mail. See Bug 140212 (/ in folder name) and Bug 117840 (ending dot). "CPU 100%" is caused by Bug 140212. See also dependency tree of Bug 124287, which is showcase of problems relate to special characters in folder name. You can choose any problem you want ;-)

Thunderbird does nothing when trying to create folders with a "/" in it (from what I have found). I was going to post a new bug but my purposed resolution to this bug would fix both (similar) bugs. Thunderbird should do some input validation while creating folders IMHO. - Mick (o> Web / software developer ( ) UNIX Systems Admin --- ~ www.mickweiss.com ~

Just stumbled over this, too. Using Thunderbird 1.0 (20050114) on Windows XP, I created a folder "BeOS/Haiku" :) and Thunderbird created a folder "BeOS" with a subfolder "Haiku" in it, all at once. I had no problems with the new folders, but this was obviously not what I wanted, so I just deleted the subfolder without problems. Could be a feature;), but then Thunderbird should ask the user. Better would be to perform input-validation like Mick suggested, just like the OS does when entering file/directory-names.
