[bt full included] imap-login: Panic: file client-common.c: line 272 (client_destroy): assertion failed: (client->create_finished)
Hi,
as discussed with cmouse on freenode two days ago please find attached
necessary debug information on a crashing imap-login process, that
appeared after upgrading to v2.3 (+ sieve). It is a standard setup in
combination with postfix and thunderbird, roundcube and K9(Android) as
imap clients. Panic happens 5-6 times a day, but no influence on user
experience. Unfortunately i have no idea what might be causing it.
Let me know if you need more information.
Andreas
