-------------------------------------------+------------------------
Our user model pk is a UUID, while making some tests trying to reset the
password, we met a 500 because the encoded UUID is not decoded properly.
Here's the URL:
http://127.0.0.1:8000/reset/MTgiYWRiYmItZWNhYi00OTBiLThiMTMtYzg0MDUxMWRmOTVl/4u3-853c9fe868a403fa439f/
and this is the traceback:
{{{

}}}
The error is raised when **user = UserModel._default_manager.get(pk=uid)**
is executd, while I think a ValidationError is a proper exception I'm
wondering if that couldn't be catched within that try/except. I feel is a
bit weird getting a 500 if somebody tries to forge a URL for example.
