Application that crashed: kdevelop.bin
Version of the application: 4.0.0 (using KDevPlatform 1.0.0)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
pressed the button "debug current launch" => kdevelop crashed
this happened serveral times, but it's not constantly reproducable, so I have no clue when this happens and when my launch is just debugged as expected.

 -- Backtrace:
