Application: kontact (4.9.5)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-27-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

Right after syncing with Google Calendar (created a new task list and renamed another one) I tried to switch between lists. Then it crashed.

The crash can be reproduced some of the time.

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