Mcop

When trying to run xine on Debian I was getting an error:

$ xine tpb.mpg 
This is xine (X11 gui) - a free video player v0.99.5cvs.
(c) 2000-2004 The xine Team.
can't create mcop directory
$

so I tried to find the culprit:

$ find /home -iname "*mcop*" -exec ls -l {} \;

which had too many files to manually parse. After some further inestigating, it appears to be related to audio. Something else has the audio locked, in my case I was listening to mp3s with xmms at the time. Once I close xmms, all was well.
