Is there a patch to fix MultiValueDictKeyError on matching_tags page?

Hello,

I've downloaded the last version of code and installed it on my server. Now, every time when Googlebot access my web, it access /matching_tags page and raises MultiValueDictKeyError. The whole traceback is here:

Traceback (most recent call last):

File ".../django/core/handlers/base.py", line 100, in get_response
   response = callback(request, *callback_args, **callback_kwargs)

File ".../osqa/forum/views/commands.py", line 513, in matching_tags
   if len(request.GET['q']) == 0:

File ".../django/utils/datastructures.py", line 235, in __getitem__
   raise MultiValueDictKeyError("Key %r not found in %r" % (key, self))

MultiValueDictKeyError: "Key 'q' not found in <QueryDict: {}>"

The problem is in forum/views/commands.py at line 513:

if len(request.GET['q']) == 0:
        raise CommandException(_("Invalid request"))

If q is not in GET request, the exception is raised. In my opinion, this code is better:

if len(request.GET.get('q', '')) == 0:
        raise CommandException(_("Invalid request"))

But there is still problem with unhandled exception in view. So I change code above to this:

if len(request.GET.get('q', '')) == 0:
        return HttpResponseBadRequest("Invalid request")

Is there any official patch to this?
