I quickly check the source (and no time today), but I often observed this problem, when modules loaded from sys.modules (see mediaglobin/init/plugins/__init__.py).

It's not easy to debug. The best way (and time consuming) is to load each modules (and submodules) up to mediagoblin/media_types/audio/transcoders.py in comparison to the output of sys.modules (it's dictionary).

For example I easily fixed circular import for a new port, called Flowblade (it's a video editor, not yet in ports tree), but I can't find solution for Pitivi (another video editor).

After all it's perhaps Numpy's problem, but nobody reported this issue.
