I deleted this file and tried running mnemosyne with python-matplotlib
1.3.0-1 and this resulted in exactly same error as before. But then
after downgrade to 1.1.1~rc2-1 I got different error:

"
$ mnemosyne
Value error parsing header in AFM: ItalicAngle -15,5
An unexpected error has occurred.
Please forward the following info to the developers:

Traceback (innermost last):

    if font.get_angle() != 0 or name.lower().find('italic') >= 0:
  File "/usr/lib/pymodules/python2.7/matplotlib/afm.py", line 468, in get_angle
    return self._header['ItalicAngle']
 KeyError: 'ItalicAngle'
"

This seems to be  very similar (if not identical) to the one reported
in the #691916.
Unfortunately (for me) mnemosyne actually depends on python-matplotlib
so removing it won't fix my problem.
