Why can't I import fixtures from 'dump_forum' V 0.7.47?

dump_forum
fixtures
bug
retag add tags

I can't seem to import fixtures created by forum_dump.

To confirm this I created a new database with 1 user and 1 question.

I then:

$ python manage.py dump_forum

$ python manage.py flush

$ python manage.py load_forum test_dump_delete

WARNING!!! You are using a 'locmem' (local memory) caching backend,
which is OK for a low volume site running on a single-process server.
For a multi-process configuration it is neccessary to have a production
cache system, such as redis or memcached.

With local memory caching and multi-process setup you might intermittently
see outdated content on your site.
