Application that crashed: akonadi_gcal_resource
Version of the application: 0.1
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was removing one duplicated google calendar resource and the crash was presented to me. However, Kontact was still running after Dr. Konki appears with the backtrace. I downloaded the dbg packges to show a 3 stars backtrace, reported this bug and after that I'm using the same Kontact process that caused the bug without any problem.

 -- Backtrace:
Application: Akonadi Resource (akonadi_gcal_resource), signal: Segmentation fault
