Sentry Crash Report:

Description retired 2012-08-05 17:58:25 UTC 
Application: rekonq (0.9.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I've been changing icon packs in Kubuntu x64 12.04 LTS with all updates for 5th August and then it suddenly crashed.
My actual version of KDE is so damn unstable.

-- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault

Comment 4 Hugo Pereira Da Costa 2012-09-07 14:02:02 UTC 
Patch above (pushed both to master and KDE/4.9) should fix the crash.
I could not reproduce it (I guess its the result of some race condition), but the patch makes sense, and the check on transitionWidget should be done there, as done elsewhere in the same code (especially since a QWeakPointer is used).
I guess one should leave the bug open for a while, though, to give a chance to people reporting to test.
