[Python-modules-team] Bug#498953: closed by Torsten Marek <shlomme at gmx.net> (Closing the bug)

Thu Nov 20 11:17:22 UTC 2008

Hi,

I just did a full update/upgrade/distupgrade and found that my versions on python-opengl 
and python-2.5 were equal to or greater than those you mentioned. The bug still occurs.

Before we write this off as system specific, can you tell me if anything's up/what version 
you have of python-ctypes? I suspect the problem might be there somewhere.

I need to reinstall soon anyway, I'll do a fresh install some time in the next month or 
two and bug you again if I can reproduce it.
