quack

If the shared files index references a nonexistent file
an infinite loop results with the message:

[Errno 2] No such file or directory: '<filename>'

Killing (with ^C) provides:

Traceback (innermost last):
File "./quack", line 32, in ?
share.loadIndexFile('sharedfiles.qndx')
File "/usr/lib/python1.5/exceptions.py", line 106, in
__init__
self.filename = None
KeyboardInterrupt

Note that zero length files do not cause a problem.
