Bug 215576

Application: kdevelop (3.9.96 (using KDevPlatform 0.9.96))
KDE Version: 4.3.77 (KDE 4.3.77 (KDE 4.4 >= 20091120)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
it worked the first time, but when i closed main.cpp and reopened it in the project browser with double click, kdevelop crashed.

this is 4.4. build  from Sa 21. Nov 18:09:32 CET 2009
