Bug 216253

Application that crashed: kdevelop
Version of the application: 3.9.96 (using KDevPlatform 0.9.96)
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic-pae i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
When I changed the signature of a member function in the header file of a class, KDevelop crashed. I could reproduce this very often.

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