Description thomas gahr 2011-12-18 15:32:46 UTC

Application: kontact (4.8 beta2)
KDE Platform Version: 4.7.90 (4.8 Beta2 (4.7.90)
Qt Version: 4.8.0
Operating System: Linux 3.1.5-2.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed:
Closed it via ctrl+q.
Not running kmail as standalone but within kontact

- Unusual behavior I noticed:
All of kmail's views where empty - nothing in the folder view and nothing in the messagelist view or message view. Absolutely nothing.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

screenshot of kmail (kontact) before crash

This screenshot shows the broken kmail that crashes when closing

Comment 2 thomas gahr 2011-12-18 15:38:57 UTC

After logging out and back in the behaviour is gone. KMail works as expected, both in kontact and as standalone.

New crash information added by DrKonqi

kontact (4.8 beta2) on KDE Platform 4.7.4 (4.7.4) using Qt 4.8.0

Same situation: some folders were empty and the folder icons where the "spinning wheel" distraction indicating that KMail was working. I am also using it inside Kontact. When I Ctrl+Q'ed the application so I could stop and restart akonadi, KMail crashed with the same backtrace.

kontact (4.8.0) on KDE Platform 4.8.00 (4.8.0 using Qt 4.8.0

- What I was doing when the application crashed:
Closed Kontact

- Unusual behavior I noticed:
KMail could not open any mails, showing "Retrieving folder contents" only

Happens often, restarting Kontact does not change anything.
Restarting Akonadi makes the behaviour go a away. Note: restarting akonadi takes very long (about 1-2 minutes)
