When you move / remove .mozilla-thunderbird and reconfigure Thunderbird to use your pop account, does it crash again then? For me it does with IMAP.
Btw., there was no Thunderbird update for a long time now: https://launchpad.net/distros/ubuntu/+source/mozilla-thunderbird/ so I guess the crash is caused by an email we have in our mailbox. -- [Edgy] Consistent crash on start when connecting to IMAP server https://launchpad.net/bugs/63653 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
