I guess the problem is the async part, meaning that the function will return
before the callback has actually been called. This function doesn't seem to
have a "destroy user data" callback parameter so the user_data would have to
survive _forever_. Of course C Apps often have global stuff like that. It
looks like a bug in the libbonoboui API. I suggest patching in an API
addition for us.
