*** Bug 263134 has been marked as a duplicate of this bug. *** if you can reproduce this, please run kdevelop through valgrind: valgrind --log-file=/tmp/kdevelop.memcheck.log --track-origins=yes --num-callers=50 kdevelop and attach the log file here. Created attachment 56120 [details]
New crash information added by DrKonqi
kdevelop (4.2.60) on KDE Platform 4.5.5 (KDE 4.5.5) using Qt 4.7.1
- What I was doing when the application crashed:
just closed kdevelop
will try to reproduce with "valgrind --log-file=/tmp/kdevelop.memcheck.log --track-origins=yes --num-callers=50 kdevelop
"
-- Backtrace (Reduced):

So I could gather some valgrind output (beware it's a RelWithDebInfo build so some uninitialised reads might be false alarms).
