Description Lorenzo Villani 2009-05-29 17:24:58 UTC

Application that crashed: kdevelop
Version of the application: 3.9.93 (using KDevPlatform 0.9.93)
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.6.0
Operating System: Linux 2.6.29.4-162.fc11.i686.PAE i686

What I was doing when the application crashed:
Shortly after opening a project (and a source file) KDevelop 4 crashed.

Comment 1 Andreas Pakulat 2009-05-29 17:53:12 UTC

Where did you get Qt 4.6.0? There's no such thing. 

Apart from that the backtrace looks kinda broken, the shown line in browsermanager.cpp doesn't call the qmap destructor. Can you reproduce this crash? If so please try running kdevelop in valgrind to get more useful information regarding any memory-problems.

Comment 2 Lorenzo Villani 2009-05-29 18:49:13 UTC

> Where did you get Qt 4.6.0? There's no such thing.
Qt from git

> Apart from that the backtrace looks kinda broken,
Forgot to install the debuginfo package, my bad

> Can you reproduce this crash?
Nope.

Ok, then please refrain from reporting bugs against kdevelop until you switch to a stable Qt release (or at least to the stable branch in the git repo).

Then I'm closing this, especially with the unstable Qt being used.
