occasional crash

[tshirtman]

I'm not sure yet of the cause, i though it was going to suspend mode, but i just tested and apparently not, anyway, this happened two times already, every time after a long period of use.

Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python3.5/threading.py", line 914, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.5/threading.py", line 862, in run

    window_name = active_window.get_full_property(self.NET_WM_NAME, 0).value
AttributeError: 'NoneType' object has no attribute 'value'

edit, happened again during/after a longer period of sleep, so i'm not sure.
