Problems with AFM fonts.

The example is (under Windows XP, Matplotlib 0.86.2, using Tkinter after making a "clean" matplotlib installation):

from pylab import *

Until now everything is OK.
When I press SaveFigure button in the NavigationToolbar the error messages are:

Exception in Tkinter callback

IOError: [Errno 2] No such file or directory: 'D:\\Python24\\share\\matplotlib\\phvr8a.afm'

Obviously, there are no "*.afm" files in the "D:\python24\share\matplotlib\" directory.
To be exact, there isn't even a "D:\python24\share\matplotlib\" directory!
The same script runs fine when rcParams['ps.useafm']=False
The same bug (?) seemed to exist in Matplotlib 0.86.1.

Thanks for the support,
