Thanks, ctypes is actually a great idea, I should have thought about that.
In the meantime I use the simple function

def get_local_path_from_uri( uri ):

    return uri.split( '//' )[1]


and it seems to work. In the program the function is always called in
a try: except: block so if anything is not okay it will get caught, I
don't have to catch exceptions inside the function.

Cheers,
Daniel
