Thanks,
Massimo, I'm away from my ubuntu machine right now, so I can't test
this. In the meantime, try in ipython
xmode verbose
before running your code. This will generate a more detailed
traceback, which might give us some clues.
I noticed that I get the error only when I write on a FAT32 partition
that I use to exchange file with Windows. Writing on my /home ext3
partition gives no error.
I guess MPL is trying to put some attribute on the saved file that is
not supported by FAT32.
Down here there's the "xmode verbose" traceback
In [11]: savefig('prova.eps')
