Application that crashed: kdevelop
Version of the application: 3.9.93 (using KDevPlatform 0.9.93)
KDE Version: 4.2.91 (KDE 4.2.91 (KDE 4.3 >= 20090609))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-ARCH i686

What I was doing when the application crashed:
There really is not much information I can say about this crash. The only thing that I really did was open up kdevelop, then load a cmake project that I had loaded before(kdebase/runtime) via the recent projects menu, then looked around in a file. The project finished loading as I was browsing that file, then it crashed. Hopefully this report is of use. Unknown reproducability.
