Historicaly removed app raises django.core.exceptions.ImproperlyConfigured

I'm using "trunk" version 617:b52d5e1e4b21 of south. And it seems there is a bug in ignoring missing applications.

./manage.py migrate

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: App with label transactions could not be found

I think that check_migration_histories() shoudl call h.get_migration() in try/except block as well. (Patch attached.)
