xmms crashing at startup

[Manolis Kiagias]

I believe this started after upgrading to Xorg-7.3:

sonic at freebsdgr:~$ xmms
Gdk-ERROR **: BadMatch (invalid parameter attributes)
  serial 1492 error_code 8 request_code 72 minor_code 0
Gdk-ERROR **: BadMatch (invalid parameter attributes)
  serial 1493 error_code 8 request_code 72 minor_code 0

I tried uninstalling and recompiling the port, nothing changed.
I also can't find anything meaningful about this in Google. Any ideas?
