Description RJVB 2016-09-10 20:47:46 UTC

Application: kdevelop (5.0.0)
 (Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

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

I just uploaded a new patch to ReviewBoard using the patchreview plugin's export feature. I then quit KDevelop without closing the patch review first. That omission causes a systematic crash on OS X.

The crash can be reproduced every time.

-- Backtrace:

Comment 2 Milian Wolff 2016-09-13 21:17:49 UTC

crashes deep inside Qt, please report upstream

Comment 3 RJVB 2016-09-13 22:13:18 UTC

A crash deep in Qt can occur because of something done wrong in the dependent code; are you sure that's not the case here?

Can you reproduce the issue?

Comment 4 Milian Wolff 2016-09-21 09:55:47 UTC

The crash clearly points towards QQmlApplicationEngine which has zero to do with the patch review code and no I cannot reproduce this.
