Public bug reported:

Binary package hint: fonttools

The checksum writing code does not bound to the range 0..0xffffffff
needed for sstruct in Pythong 2.7, resulting int trying to write (32-bit
hex values such as) -685515063 for the 'checkSum' field:

  File "/usr/lib/pymodules/python2.7/FontTools/fontTools/ttLib/__init__.py", line 203, in save
    writer.close()
  File "/usr/lib/pymodules/python2.7/FontTools/fontTools/ttLib/sfnt.py", line 153, in close
    directory = directory + entry.toString()
  File "/usr/lib/pymodules/python2.7/FontTools/fontTools/ttLib/sfnt.py", line 224, in toString
    return sstruct.pack(sfntDirectoryEntryFormat, self)
  File "/usr/lib/pymodules/python2.7/FontTools/sstruct.py", line 79, in pack
    data = apply(struct.pack, (formatstring,) + tuple(elements))

The solution is probably to use something like checksum ^ 0xffffffff
during preparation.
