Application: amarok (2.4.0)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.37-gentoo-r4 x86_64
Distribution: "Gentoo Base System release 2.0.2"

-- Information about the crash:
- What I was doing when the application crashed:

I was playing with volume control via pulseaudio/veromix and the media controls on the keyboard.

- Unusual behavior I noticed:

When the volume reached zero, the stream from amarok seemed to crash, as pulse displayed a new stream near it after it restarted. It took a lot of trials after reaching 0 volume to get the volume back up.

- Custom settings of the application:

Veromix is configured NOT to mute the channel when reaching 0 volume.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted
