Description Jeppe Fock 2009-06-11 17:39:45 UTC
Version:           Kontact: 1.4.2 (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

Kontact crashes at random.  It happens to me multiple times a day, but I can find a systematic event which courses the crash. 

When restarting kontact the last state of kmail is restored, except for the marking of some of the read mails as unread.

Application: Kontact (kontact), signal SIGSEGV

Comment 1 Christophe Marin 2009-06-12 11:55:56 UTC
Maybe related to bug 124372
Comment 2 Jeppe Fock 2009-07-06 18:41:46 UTC
After a clean reinstall of Kubuntu juanty, kontact/kmail still crashes with the same traceback.  I don't see any relation to bug 124372, but I'm no developer.

I will be happy to provide further details for the bug to be solved.

Backtrace of bug
Comment 4 Jeppe Fock 2009-07-08 10:09:54 UTC
When stating kmail directly (instead of stating kontact), a slightly different backtrace is produced. I have attached the backtrace here. Please ask  for more details if needed.

details if needed.
Comment 6 Christophe Marin 2009-07-18 17:58:01 UTC
Do you have a pre-command set for this account ? (kmail/settings/Configure KMail/Accounts and the "Advanced tab"
Comment 7 Jeppe Fock 2009-07-18 18:53:29 UTC
Yes I have two accounts each calling a script which connect to a the specific server. The script contains:

ssh -C -f username@server -L 2025:localhost:25  -L 2110:mail.server:110 'sleep 5'; sleep 1
Comment 8 Martin Koller 2009-08-31 23:48:11 UTC
SVN commit 1017922 by mkoller:

BUG: 196053

Fix crash in precommand execution (hopefully).
The crash was probably due to the eventloop object got destroyed in its own loop.
