Overview Description: This is a sporadically-appearing bug -- I've seen it maybe five or so times today. Steps to Reproduce: 1) Single-click on an IMAP folder. Not necessarily the first folder selected for that server, not necessarily not. 2) Alternatively, I also had this happen when I had several POP and IMAP accounts expanded and I double-clicked on the top-level "Accounts" line in the folder pane in an attempt to collapse all accounts. Actual Results: Crash. See stack below. Expected Results: No crash. Build Date & Platform Bug Found: 7_8 Linux build. Additional Builds and Platforms Tested On: None. Additional Information: Only tested on Linux so far. I know I've seen it when testing against the server zia, which is the third server in my list (POP, IMAP, IMAP) Fenella, what server were you testing against when you saw it (as reported in bug 8572?)

Sorry; adding [PP], since it is as far as we know it at this point. Setting priority to P2, since it's a crasher, but not an easily-reproducible one.

I this may be the same of all those crash when selecting IMAP server/folder bugs we have open. http://bugzilla.mozilla.org/show_bug.cgi?id=9365 http://bugzilla.mozilla.org/show_bug.cgi?id=9398

Ah, OK. Yuck. We seem to have lost a great deal of stability since M7. I'll mark this a dupe of 9398. *** This bug has been marked as a duplicate of 9398 ***
