Application: kwrite (4.9.1 "release 561")
KDE Platform Version: 4.9.1 "release 561"
Qt Version: 4.8.3
Operating System: Linux 3.1.10-1.16-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

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

I started KWrite and it crashed. Same behaviour happens with other applications related to Kate, for example Kile. Not always the applications crashed, and the times they not crashed they worked seamlessly. Crashes occurs often when a lot of other applications are open, while when few or no other applications are open KWrite doesn't crash. It must be noted that if I can start KWrite and then start a lot of other applications, KWrite continues to work seamlessly. The bug must be in some part of the code executed almost only on application start.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KWrite (kdeinit4), signal: Segmentation fault
