Hi,

Georg Wittenburg reported in Debian bug <http://bugs.debian.org/296751> that he
experiences trouble with alsasink in amarok.

It seems to be related to his Alsa configuration.

Quoting his report:
"GStreamer crashes when used by Amarok 1.2.0. The console says:

He completed this information with the following:

Note that my ALSA pipeline is setup as default -> plug -> asym -> dmix ->       
card0 -> hw:0. The "plug" seems to be the relevant part. When I access the      
hardware directly, I get crashes:

This is with GStreamer 0.8.9, and might be with gst-plugins 0.8.6, I'm waiting
for a confirmation of the gst-plugins version (it might be with 0.8.7).
