Sentry Crash Report:

Description JoseLuisT 2013-01-29 03:35:23 UTC 
Application: systemsettings (1.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-36-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Testing the speakers, actually I had sound on them. 

I did the test after killing pulseaudio and restarting the sound module, this way; as root: 

ps ax | grep pulseaudio 
kill <pulse-pid> && rmmod snd_hda_intel 
modprobe snd_hda_intel

- Custom settings of the application:
No custom settings of the application itself, I use oxygen-transparent style. 

- other information: 
I noticed that my sensors ( I use Yasp Scripted) does not give the information as it does normally, instead of having CPU load, It shows zero all the time, and my graphic card is 4 celcius degrees up to normal (now is 53, normally is 49)

-- Backtrace:
Application: Preferencias del sistema (systemsettings), signal: Aborted

Comment 1 Christoph Feck 2013-01-29 12:18:56 UTC 
Widgets cannot be accessed outside the UI thread (main thread). The canberra/pulseaudio callback in phonon/kcm/testspeakerwidget.cpp:27 needs to be refactored to signal the main thread for UI changes.
