Try switching to the Ps backend by putting:
import matplotlib
matplotlib.use("ps")
at the top of your script. That will take gtk and its popup windows out
of the equation.
After doing that, you should get a traceback at the terminal that should
help narrow this down. At this point we can only guess, without a line
number.
Can you also provide a minimal script that causes this error? I'm
particularly puzzled by the difference in output between PDF and PS.
Cheers,
Mike
