Different kinds of Import Errors

[Thomas Guettler]

If you look at this code, you see there are two kind of ImportErrors:

1. app_name has no attribute or file managment.py: That's OK.
2. managment.py exists, but raises an ImportError: That's not OK: reraise

        # Import the 'management' module within each installed app, to register
        # dispatcher events.
        for app_name in settings.INSTALLED_APPS:
            try:
                __import__(app_name + '.management', {}, {}, [''])
            except ImportError, exc:
                if exc.args[0]!='No module named management':
                    raise


I am searching a better solution, since in a future version of python
the string 'No module namend management' might be changed.

Any better solution?
