add_font is broken in 1.54b

[GoogleCodeExporter]

I convert ttf font for cp1250 codepage with makefont.py tool from pyfpdf 
package and when I try to add this font to my document, I got error:

pdf.add_font('CourierNewPSMT','','cour.py')

  File "/work/pyfpdf/pyfpdf-1.54b/fpdf.py", line 445, in add_font
    self.diffs[d]=diff
IndexError: list assignment index out of range

I made quick fix to solve problem, I will put fixed version of fpdf.py in 
attachment.
