Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was scrolling on the list of my Gmail e-mails. Can reproduce in any folder but only a while after turning on my computer. Once Kontact crashed once it does so everytime I scroll until I restart the computer.

I'm running Kubuntu 11.10 with latest KDE SC backports. Crash seems to only happen with Gmail account.

The crash can be reproduced every time.

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