Description Bastian 2012-09-21 19:19:04 UTC

Application: kdevelop (4.4.60)
KDE Platform Version: 4.9.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-15-generic x86_64
Distribution: Ubuntu quantal (development branch)

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

I inserted this line:
   void setResultSet(engine::IResultSet * result);
As I closed KDevelop, the background parser was still active.
This crash happens sometimes and I could not reproduce it.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Probably a QML bug :-/ If you could reproduce this with valgrind that would be very helpful...

valgrind --track-origins=yes kdevelop -s ...

Comment 8 Kevin Funk 2013-02-05 10:58:02 UTC

That seems to be fixed with Qt 4.8.4.

Reasons for that - multiple bug entries show the same symptoms (backtrace) and have been set to UPSTREAM.
- https://bugs.kde.org/show_bug.cgi?id=311018
- https://bugs.kde.org/show_bug.cgi?id=300393

I have been running KDevelop with Qt 4.8.4 for quite some time now and didn't experience any QDeclarativeItem related crashes anymore.

Please reopen if this is reproducible with Qt >= 4.8.4

Comment 9 Laurent Bonnaud 2013-02-05 15:52:01 UTC

I confirm that with Qt 4.8.4 in Ubuntu raring this bug is gone.

Comment #10 is from Qt 4.8.4, so the bug is still not fixed.

This bug might still be present with Qt 4.8.4. See for example bug 324480. It has two reports of a crash with QT 4.8.4.

Comment 20 Kevin Funk 2014-01-29 13:37:25 UTC

I really can't tell what's going on here. AFAIR, I had the same problems in <4.8.4 times, but the crashes went away after upgrading to 4.8.4. Nowadays I'm running 4.8.5. I've never had this kind of crashes for anything >=4.8.4, though.
