New crash information added by DrKonqi
kdevelop (4.1.60) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0
- What I was doing when the application crashed:
I just want to switch to another session.
Note: Today on 08.10.10 i do a fresh checkout of kdevplatform and kdevelop from git and build it by my own. So the bug cannot be fixed yet.

hm if that is reproducible, run kdevelop through valgrind please: valgrind --track-origins=yes kdevelop Hello, i have try this, and will give one more note: the error did only occour if i git update some projects (from an external konsole) that are open in the kdevelop session and then switch to another session it crashes. i'am not sure how i can use valgrind to dump the needed infos... maybe you can tell me...but valgrind has detects something.. look at the end of attachment.
