usetex w/ preview.sty

Sorry about the wild good chase. I had fixed up an earlier exception which was simply a problem with formatting a verbose message. That gives this, when running usetex_fonteffects.py (with all rcParams at defaults):

Traceback (most recent call last):
  File "usetex_fonteffects.py", line 22, in <module>
    pylab.savefig('usetex_fonteffects.pdf')

Do an SVN update (r6736) and try again. Then I get this:

> python usetex_fonteffects.py
Traceback (most recent call last):

    file = open(input, 'rb')

So somehow, input is None, but I haven't had a chance to look any further.

Cheers,
Mike
