-- Information about the crash:
- What I was doing when the application crashed:
I was in the Phonon configuration and I was testing my speakes by pressing the
"Front Left" and "Front Right" buttons.

I Changed the connector from "Headphones" to "Speakers" and I got this crash.

I tried a couple of times to reproduce the bug, but I could not succeed to make
it crash again.
