KDE Platform Version: 4.5.85 (4.6 Beta2)

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

Changing the size of the icons of the side bar. The backtrace is very different to the one I marked as a possible duplicate. Maybe this is a different bug?

The crash can be reproduced some of the time.

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