Comment 1 for bug 562111

This error means there is some logging being used before logging is configured. Configuration happens early on zim.__init__.py main() .

My suspicion is that somehow in the compiled version modules are loaded in a different order so a warning is emitted before this main() function is called.

You can try putting the following code at the start of zim.py and compile it again:

  import logging
  logging.basicConfig()

Hope this helps.
