"no such column" database error in admin

I'm trying to use the admin interface, and while it's working for my User object, when I try to access the Event object I get this:

Request Method:	GET
Request URL:	http://localhost:8000/admin/test1/event/
Django Version:	1.5.4
Exception Type:	DatabaseError
Exception Value:	no such column: test1_event.track
Exception Location:	C:\Python33\lib\site-packages\django\db\backends\sqlite3\base.py in execute, line 362
Python Executable:	C:\Python33\python.exe
Python Version:	3.3.2

Event does have a foreign key referencing User; I've seen other posts about that causing complications, but not this specific one.

I've tried resyncing the db, but it doesn't help.

Thoughts?

Thanks!
