im pretty new to python, and i know nothing of latex, other than it seems to be well broken atm for me. i can save figures in any other file format with no errors.

i've asked friends (other distros) and the folks in #scipy, noone else seems to have this problem.
i'd bet it has something to do wiht my setup, but im afraid idk enough to fix this problem.
