Application: kwrite (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

Tried to open the "About App" dialog (for example, Help -> About App). This happens to any KDE app on my system. The crash logs look similar.

However, the Help -> About KDE command does not cause a crash.

The crash can be reproduced every time.

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