"source" re.sub fails on default None

[GoogleCodeExporter]

It seems that a non-matching groupdict() can cause source to be None, which 
throws the error below. I'm using Python 2.6 on AutoSub 0.3.
Note: I don't code Python, but a similar issue might pop up on line 85.

nas> python2.6 AutoSub.py 
Traceback (most recent call last):
  File "AutoSub.py", line 130, in <module>
    sys.exit(main())
  File "AutoSub.py", line 92, in main
    wantedQueue = LocalDisk.scanDir(config.rootpath)
  File "/volume1/AutoSub/LocalDisk.py", line 74, in scanDir
    filenameResults = Helpers.ProcessFileName(filename)
  File "/volume1/AutoSub/Helpers.py", line 74, in ProcessFileName
    source = re.sub("[. _-]", "-", source)  
  File "/opt/lib/python2.6/re.py", line 151, in sub
    return _compile(pattern, 0).sub(repl, string, count)
TypeError: expected string or buffer
