Potential Issue during answer edit
One of my user got an exception:
UnboundLocalError at /answers/451/edit/ local variable 'revision_form' referenced before assignment
The error is during the POST in askbot/views/writers.py in edit_answer, line 435 (setting the 'revision_form' of the data dictionary).
Looking at the code, it appears that the test "if form.is_valid():" (line 419) returned false.
I don't know what the user did to not get a valid form, but should probably catch that case.
