I guess it would be a lot easier to figure out exactly what happens if you could provide at least a backtrace of the crash reported.

Comment 2 Hugo Pereira Da Costa 2014-01-13 09:27:40 UTC

Can reproduce. Backtrace:

I believe it might also be related to the other (invisible panel) bug.
Only happens if one of the side panels has been made visible.

New crash information added by DrKonqi

gwenview (4.12.0) on KDE Platform 4.12.0 using Qt 4.8.4

- What I was doing when the application crashed: I have already made my bugreport earlier.

Comment 4 Christoph Feck 2014-01-14 02:15:10 UTC

Hugo, does oxygen-transparent use a global QWidget? See also bug 261539, which is caused by a global QWidget from Qt and from KIdleTime.

Comment 5 null 2017-12-10 20:25:51 UTC

Hugo: Trying to reproduce this, I could not find any Qt5 version of Oxygen Transparent (the kf5 branch is almost 4 years old and does not even configure correctly). Is this ever planned to come back or can we close this crasher bug (if the crash is not a generic issue)?

Hi, 
there is no plan to have an "oxygen-transparent" for Qt5/kf5 (in fact I think qt5 makes it pretty difficult). So you can safely close the bug report.

Best,

Hugo

Hugo: Okay, thanks.

Jacobtey: Sorry we could not solve this for you. I hope you found another style you are happy with in the meantime.
