The exception gets thrown from time to time when doing something with
windows, like creating them. Will have to look in this more deeply,
concerning the apparently non-deterneministic nature of exception throwing.

To me it seems that they are related, but as I don't get segfaults, It
should be possible for also.

I tested with a setup that differs only with glibc being v. 2.3.6 (I'm
using debian testing). Still, pywm just keeps going, only complaining
from time to time. What do you think is causing the segfaulting? Could
you maybe test with differrent setups (different distros especially)

Anyway, I'll try to fix the bug soon.
