xmms, kjofol and deadlock

I am using xmms 1.2.10 compiled from source, and kjofol visualisation
plug-in from:
  http://www.csse.monash.edu.au/~timf/xmms.html

Everything works fine except, when using a kjofol playlist editor to
add tracks or remove tracks.

The problem is that xmms locks up - it turns out to be a threading
issue, and xmms is hanging on a call to GDK_THREADS_ENTER()

What happens is when the kjofol play list is modified, and a track
either added or removed then several "remote" calls are made to xmms,
the first of which is to clear the playlist. This results in:
  void *ctrlsocket_func(void *arg) in controlsocket.c 
being called, which then enters the CMD_PLAYLIST_CLEAR section of the
case statement, and GDK_THREADS_ENTER() blocks.

The only two cases that use GDK_THREADS_ENTER() are the CLEAR and the
DELETE just above it - but these two cases do mess around with gdk
stuff so it seems like the thread lock is justified.

I was wondering if anyone could suggest why xmms might be deadlocking
at this point, I know (guess) that the problem must be something to do
with the combination of XMMS & kjofol but as kjofol doesn't seem to
perform and thread locking I am at a loss to see why it should be the
cause.

I haven't had too long to look into the problem yet, but I hope
someone might know the answer and save me the bother.

Thanks
