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)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5 x86_64

What I was doing when the application crashed:
I had created a new project and had removed the automatically added main.cpp from it, leaving no source files. I then added a new source file to the project and wanted to add it to CMakelists.txt manually. This caused KDevelop to crash

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