Description Jordan Cran 2015-01-29 07:03:31 UTC 
Application: systemsettings5 (5.2.0)
 (Compiled from sources)
Qt Version: 5.3.2
Operating System: Linux 3.14.29 x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Changing *any* settings under the font section crashes system settings when the apply button is clicked.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault

Comment 1 Jordan Cran 2015-01-30 02:38:26 UTC 
I can apply settings in the workspace themes and icons sections and they have not crashed so far. Anytime there is a crash in system settings, I briefly see a modal dialog appear, slightly wider than the system settings window. Maybe some kind of a system sound effect is usually played when these dialogs open - and thats why:
#5  0x00007fe2031f1617 in Phonon::Gstreamer::MediaNode::linkMediaNodeList(QList<QObject*>&, _GstElement*, _GstElement*, _GstElement*) () from /nix/store/z6fy5fn1g0xzrr0zhqz7v1y079a9n720-phonon-backend-gstreamer-4.8.2/lib/qt5/plugins/phonon4qt5_backend/phonon_gstreamer.so
Appears in the stack trace?
Comment 2 Jordan Cran 2015-01-30 03:12:33 UTC 
Konsole and a few other applications have crashed a few times - each time Phonon::Gstreamer::MediaNode::... etc is first in the stack trace.  So this isn't specific to System Settings as far as I can tell. If I open system settings, Notifications, and then select "Local system message service" as the event source (only because this contains an event that by default plays a sound) and click the test sound button, System Settings crashes with the same Phonon gstreamer backend calls.
Comment 3 Pierre Willenbrock 2015-02-23 18:43:55 UTC 
Maybe this is a case of two versions of gstreamer being pulled into the same process: qtwebkit seems to pull in gstreamer-0.10 if configured for using gstreamer, and phonon pulls gstreamer-1.x. lsof -c systemsettings shows all files opened by systemsettings, If there anything like libgstreamer-0.10 in there, both versions will be present in that process once it tries to play a sound.

I don't know if that happens for you, or if that configuration is supposed to work, but i recompiled qtwebkit without gstreamer and kde sounds worked again, for me.
Comment 4 Daniel Vrátil 2015-04-06 22:41:34 UTC 
Could you run systemsettings5 from konsole, reproduce the problem and see if it outputs anything just before the crash?

Daniel, unfortunately I am no longer using KDE. For more information, I was
using KDE on NixOS, and NixOS handles packages a little differently to
normal, and I wasn't familiar with it at that point. It is possible I
installed KDE incorrectly, but as Pierre seemed to have the same issue, I
doubt the issue was caused by me installing KDE incorrectly.
