Problems install on ubuntu 9.04

Hey I've installed osqa on ubuntu.

I'm using python2.6 and have installed South, when I run the server I don't get any errors but as soon as I make a request to osqa this is returned.

Traceback (most recent call last):

File "/usr/local/lib/python2.6/dist-packages/Django-1.1-py2.6.egg/django/core/servers/basehttp.py", line 279, in run
    self.result = application(self.environ, self.start_response)

AttributeError: 'str' object has no attribute 'get'

I was wondering if anyone has come across anything similar.
