- What I was doing when the application crashed:
Have dual monitor set up with HDMI(with functioning sound) to tv from nvidia geforce 9500GT as well the VGA(set as default monitor) with sound from Mother board sound out (back port/jack) that is not functioning. I went to system-settings>Multimedia>Phonon, Crash! 
- Unusual behavior I noticed:
Over lapping sound through HDMI only ALSO has happend three times.
- Custom settings of the application:
Kubuntu 12.04 latest updates

-- Backtrace:
