Failure with polling client in MPD network code

[adamcik]

while sleep 1; do mpc status; done manages to trigger:

Traceback (most recent call last):
  File "/home/adamcik/dev/mopidy/mopidy/utils/network.py", line 272, in recv_callback
    self.disable_recv()
  File "/home/adamcik/dev/mopidy/mopidy/utils/network.py", line 236, in disable_recv
    gobject.source_remove(self.recv_id)
TypeError: an integer is required

Can't reproduce in 10 minutes of running the while loop.

I can reproduce this with:
while true; do mpc next; done

I can't see any consistency in when it happens, but it happens fairly often. Often after 20-50 iterations, sometimes more.

I can't seem to reproduce this with the status command.

Hopefully fixed with the merge of PR#827.
