[yt-users] Odd path issue

[david collins]

Hi there--

I have this odd problem when trying to save a projection.  I do

pc.add_projection(field,axis)
pc.save(name)

on newly made projection (not one taken from the cache in X.yt file)
and it gives me the following mess:

<errstack>
    print self.pc.save(frame_template%(frame), format = self.format)
  File "/nics/b/home/collins/local_xt5/src/yt-hg/yt/yt/visualization/plot_collection.py",

    override=override, force_save=force_save))

line 18, in exists
    st = os.stat(path)
TypeError: coercing to Unicode: need string or buffer, dict found
</errstack>

pdb shows that
(Pdb) path
{'afm': None, 'ttf':
'/nics/b/home/collins/local_nautalus/src/yt-x86_64/lib/python2.6/site-packages/matplotlib/mpl-data/fonts/ttf/Vera.ttf'}

which isn't a path.

I just built from changeset 3628:da3894bf42a5.

If I then re-do the plot commands (so it reads the cached projection
off disk) it works fine.  Has anyone seen this problem?

Thanks,
d.
