Description Giorgos Tsiapaliokas 2010-12-23 23:54:41 UTC
Application: kdevelop (4.1.1)
KDE Platform Version: 4.5.4 (KDE 4.5.4) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-gentoo-r5 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
i closed the kdevelop application

- Unusual behavior I noticed:
when i log in into the kde,kdevelop always open,even if i have closed it before the last shutdown.

The crash can be reproduced some of the time.

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.

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
"

Comment 9 André Stein 2012-11-05 10:10:22 UTC
I had a situation where kdevelop crashed quite reproducebly (I had a project open and 2 extra source files). So I could gather some valgrind output (beware it's a RelWithDebInfo build so some uninitialised reads might be false alarms).

Thanks for the Valgrind report, but unfortunately that's a different bug, which has actually been fixed in git master and should be fixed in 4.4.1

This is from git master compiled today morning..
Comment 12 Olivier.jg 2012-11-05 11:44:04 UTC
