I got these errors/warnings on the server side:
Missing window or missing property or wrong property type PULSE_SERVER (latin1) Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/wimpiggy/prop.py", line 277, in prop_get data = trap.call_synced(XGetWindowProperty, target, key, atom) File "/usr/lib/python2.7/dist-packages/wimpiggy/error.py", line 101, in call_synced return self._call(False, fun, args, kwargs) File "/usr/lib/python2.7/dist-packages/wimpiggy/error.py", line 86, in _call value = fun(*args, **kwargs) File "bindings.pyx", line 484, in wimpiggy.lowlevel.bindings.XGetWindowProperty (wimpiggy/lowlevel/bindings.c:4189) NoSuchProperty: PULSE_SERVER
and similar lines for PULSE_COOKIE and PULSE_ID.
this should be fixed (by hiding the warning) in r297
Feel free to re-open if you see these messages again.
