Hmmm.  There has been a report of someone who had a similar strange problem.

I don't know the C-code well enough to make deeper sense of this. 
But it does look like your environment is seriously messed up.
I guess it is related to a third-party (C-) extension module. Are you
using any?  The other poster mentioning the problem used PyQT, do you also?
