Description margueritesu 2012-08-14 12:33:28 UTC

Application: gwenview (2.9.0)
KDE Platform Version: 4.9.00 "release 562"
Qt Version: 4.8.2
Operating System: Linux 3.4.6-1.1-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

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

* open any image
* close
* signal: Segmentation fault(11)

- Custom settings of the application:

It was triggered by Oxygen-transparent.

Oxygen or any other window decoration style doesn't have this problem.

So please bring OT dev in may help.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault

Comment 1 margueritesu 2012-08-14 12:40:39 UTC

The problem still happens after I have implemented the fix in revision e9b1714f provided by kdelibs dev in bug 303169.

Comment 2 Hugo Pereira Da Costa 2012-08-29 13:17:17 UTC

... as a workaround you can run with Qt's native graphics system.
gwenview -graphicssystem native

I'm working on finding a better workaround in oxygen-transparent.

Thanks for informing! I'll give it a try.

Comment 5 Hugo Pereira Da Costa 2012-08-29 14:04:44 UTC

That fixes it. Get latest oxygen-transparent and double-check.
closing.

Comment 6 Malte Eggers 2014-04-13 06:12:20 UTC

I would like to reopen this bug. Somehow the exact same problem described is still (again?) in the latest git master that I just updated to 10 minutes ago. Same workaround (-graphicssystem native) fixes the problem.
