Application that crashed: kdevelop
Version of the application: 3.9.94 (using KDevPlatform 0.9.94)
KDE Version: 4.3.61 (KDE 4.3.61 (KDE 4.4 >= 20090717))
Qt Version: 4.6.0
Operating System: Linux 2.6.30-ARCH i686
Distribution: "(none)"

What I was doing when the application crashed:
When starting the build of one of my CMake pet projects kdevelop crashed.

Maybe it is of importance that I'm using Qt 4.6 (from todays (2009-07-24) master git repo).
