Application: kontact (4.4.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
These problems started as soon as I switched my calendar to the Akonadi Calendar resource, before then I was experiencing no difficulties. Now the Kontact application is very unstable and prone to frequent (lock-ups) crashes. At this point Akonadi stops and I usually have to reboot in order to re-start Kontact. I will try running the Kontact applications individually to see if they behave when not running as part of the Kontact suite,.

The crash can be reproduced every time.

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