Description nickag 2015-04-13 21:59:37 UTC

Application: systemsettings (4.11.14)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: FreeBSD 10.1-RELEASE-p9 amd64
Distribution (Platform): FreeBSD Ports

-- Information about the crash:
- What I was doing when the application crashed:
I opened KDE system settings and clicked Multimedia settings when it crashed
with seg fault.

I don't know if these two are related but when opening Audio setup from
Kmix it also crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault

The same issue what I've got - crash after opening multimedia module running firstly /usr/bin/systemsettings5. I have no clue why but there is /usr/bin/systemsettings  - just without "5" at the same time and when I run it - no crash opening multimedia. It sounds like both systemsettings and systemsettings5 work in parallel. When I set startup apps or scripts - they go to systemsettings and disappear from systemsettings5! If I open notifications - all is OK until I try to play sound which set for some certain event listed, after that - crash with debugging popup. The bug is permanent - every time it is coming up over and over again.

Comment 2 Christoph Feck 2015-05-09 19:48:50 UTC

Same issue as bug 335111, but other way around. Here, a Qt4 application tries to use phonon-vlc, which incorrectly links a Qt5 plugin.
