Affects: rhythmbox (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Wanted to try to play .mpc sound files with gstreamer "bad" plugins on
Dapper.

mpc files play on totem player correctly, but not on rhythmbox.

On rhythmbox, file skips quickly until almost the end of file and then
stops. No sound is heard at all.

After playing an mpc file, rhythmbox refuses to make any sound: when
playing mp3 or radio, it seems that it is playing but no sound can be
heard. Restarting rhythmbox makes possible to play mp3 and radios again
correctly.
