kaa.metadata starts kaa main loop?

Hi,

I am trying to use kaa.metadata to read some data from multimedia files.
Since it is not a freevo related project, I have no use for most of the rest of kaa. What I do is basically:

   from kaa import metadata
   meta = metadata.parse(file)

The problem I have with this is that kaa seams to start some sort of signals handlers and other mainloop stuff that, in my case, prevents my program to quit properly.

    reactor.run()
  File "/usr/lib/python2.6/dist-packages/twisted/internet/base.py", line 1165, in run
    self.mainLoop()
--- <exception caught here> ---
  File "/usr/lib/python2.6/dist-packages/twisted/internet/base.py", line 1177, in mainLoop
    self.doIteration(t)
  File "/usr/lib/python2.6/dist-packages/twisted/internet/epollreactor.py", line 180, in doPoll
    l = self._poller.wait(len(self._selectables), timeout)
  File "/usr/lib/python2.6/dist-packages/kaa/main.py", line 313, in signal_handler
    notifier.shutdown()
  File "/usr/lib/python2.6/dist-packages/kaa/nf_wrapper.py", line 137, in shutdown
    sys.exit(0)
exceptions.SystemExit: 0

Has anyone any advice on how to prevent this?
Also, what's the point on having a metadata library if it depends so heavily on kaa as a whole?

Thanks,
Marcus
