In many cases when trying to run a program which uses python-xlib you get a
traceback similar to...
Traceback (most recent call last):

Found a solution for this on the pypanel forum from pypanel's author. To

--------------
This is a problem with Python-Xlib. Under certain conditions, the receive
buffer size isn't large enough. To fix it, open the following file -
/usr/lib/python<version>/site-packages/Xlib/protocol/display.py
and change line 530 from -
recv = self.socket.recv(2048)
to -
recv = self.socket.recv(4096)
4096 should be large enough ..
--------------
This fixed the problem I was having. I have included a patch doing just
this.
