v 0.7.48 0161 + 0162 migration

edit

I am upgrading to 0.7.48

How did junk column in askbot.thread get created?

It's not in askbot models, but first appears in 0161 askbot.thread definition. When I run schemamigration askbot --auto I get this extra migration, which is not part of 0.7.48

• Deleted field junk on askbot.Thread Created 0162_auto__del_field_thread_junk.py. You can now apply this migration with: ./manage.py migrate askbot

any ideas?
