getting error while searching for questions from home page

edit

I am evaluating askbot for use in an internal Q&A site for my team. I've got everything installed thought I was pretty much there until this. I am running django 1.3.1 and postgres 9.1.3. At first I got migration errors with ./manage.py migrate askbot. thank to http://askbot.org/en/question/6902/error-while-setting-up-askbot, I was able to get past those errors by running;

python manage.py syncdb --all
python manage.py migrate --all --fake

I can now sign in and ask questions. The problem is with searching for questions. I get this message (after putting django in debug mode). Any help getting past this is much appreciated. Here's the error:
