Bit more information:
I am also seeing warnings in app.exe.log:

I think these are all fonts that matplotlib/mathtext would use so it makes
sense that the traceback ends with:
File "matplotlib\mathtext.pyo", line 720, in _get_glyph
KeyError: 98

I then discovered that both the methods I tried for getting data_files
(using glob and matplotlib.get_py2exe_datafiles) were not working and I had
nothing in my mpl-data/fonts directory. This directory should contain 3
folders: afm, pdfcorefonts & ttf. The ttf folder is where the mathtext
fonts mentioned above are located.

I then tried manually copying the entire mpl-data folder into the dist
folder after running py2exe on setup.py but still I get the same error.

Does data_files do anything other than include files and directories in the
dist folder?
