They duplicate after restarting Thunderbird, so i need to delete one of them (this bug is reproducible, see steps). But there are more situations that i can't describe definitely. Russian folders behave crazy... it looks much like corrupted index in database. For example, now i cannot create folder "Personal" (in russian translation, of course) because when i try i get error "Folder already exists". But both of these folders were already deleted... or renamed to "Forums"... sorry i don't remember. Reproducible: Always Steps to Reproduce: 1. Install english Thunderbird 0.8 over (russian) WindowsXP. 2. Run Thunderbird and create new email account. 3. Create some folders with russian names. 4. Restart Thunderbird. Actual Results: All folders with russian names will appear twice.

please try the latest 1.0 branch build: http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/latest-0.9/ I believe this has been fixed very recently.
