Bug 218094

Application that crashed: kdevelop
Version of the application: 3.9.95 (using KDevPlatform 0.9.95)
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
The program sometimes crashes while terminating (eg. afrter close of the main window). The bug is random. I do not know exact way how to reproduce it (yet).

 -- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
