I have a similar problem but with using pkgutil.extend_path().
I have 2 packages set up a bit like this:
company/
common/
company/
apps/
news/
management/
commands/
each using the pkgutil.extend_path() trick. However only the first one on the
path will be searched for management commands.
Hopefully Nils' patch will fix this situation too
