Bug ID: 378353
Summary: System Settings crash when selecting Multimedia/Audio
and Video
Product: systemsettings
Version: unspecified
Platform: Compiled Sources
OS: FreeBSD
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: morrand...@gmail.com
Target Milestone: ---
Application: systemsettings (4.11.21)
KDE Platform Version: 4.14.10 (Compiled from sources)
Qt Version: 4.8.7
Operating System: FreeBSD 10.3-RELEASE amd64
Distribution (Platform): FreeBSD Ports
-- Information about the crash:
- What I was doing when the application crashed: Opened System Settings then
selected Mutimedia. When I select "Audio and Video Settings," System Settings
crashes about 10 seconds later without going into that settings panel.
I have recently attempted to switch from GStreamer to VLC for audio handling,
and this is likely related to that.
The crash can be reproduced every time.
-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
