Description

if i try to create a graphviz object of type svgz, i get an error that looks like: 

  File "/usr/lib/python2.6/dist-packages/trac/wiki/formatter.py", line 304, in process
    text = self.processor(text)
  File "/usr/lib/python2.6/dist-packages/trac/wiki/formatter.py", line 291, in _macro_processor
    text)
  File "/usr/lib/pymodules/python2.6/graphviz/graphviz.py", line 388, in expand_macro
    (w_val, w_unit) = w.group(1,2)
AttributeError: 'NoneType' object has no attribute 'group'

I believe the attached patch will catch this error. However, i think the right way to fix this is to do some kind of gzip import. When i do that, though (at least running through apache's mod_python), the returned file doesn't have a proper Content-encoding: gzip header, and i don't see a good way to coerce that into req.send_file().
