Created attachment 557417 [details] normal and full stack traces captured with gdb I have run a local Dovecot IMAP server. I use OfflineIMAP to sync my local Maildir with my Zimbra account. So, Zimbra --> OfflineIMAP --> Maildir --> Dovecot --> Thunderbird. Each morning when I start Thunderbird: - the status bar reports "Looking for folders..." - the mouse pointer is animated, with the well-known rotating mozilla (or gnome?) disc - originally this pointer is shown only when I hover over my folders. I can still click on menu items, for example - when I try to click on any folder, the app completely freezes (except for the rotating mouse pointer). If I Alt-Tab to another window, then back, Thunderbird can't even refresh its window anymore. - Then I go to the command line, issue "killall thunderbird-bin". Thunderbird shuts down, I restart it, and everything's fine. Until next morning. Version-Release number of selected component (if applicable): thunderbird-3.1.16-2.el6_1.x86_64 How reproducible: 100% (each morning) Actual results: Thunderbird hangs when started afresh after a longer time of non-use. Expected results: Thunderbird never hangs. Additional info: Attaching stack trace. I have also saved a core file with the gcore gdb command; ping me if you need it.

I started testing 10.0.1. For the time being the "Looking for folders" freezes seem to be gone. I'd like to give it some more time.
Works alright.
