Bug 231946

Application that crashed: kdevelop.bin
Version of the application: 3.9.99 (using KDevPlatform 0.9.99)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Simple editing of CMakeLists.txt was being done just before a crash took place.

 -- Backtrace:
