A couple users complained that they couldn't get to their authentication settings page on OSQA. They receive a 500 error. See Screenshot But, it is only after they go through the "I Forgot My Password" or after changing their password.
Looking at the log, the error specifically is:
UnboundLocalError: local variable name 'name' referenced before assignment
Has anyone else experienced this? If so, how do I fix it.
Thank you in advance for your help.!!
The Stack Trace from the log reads as follows (Sorry for the poor formatting):

Looking at the source code of osqa, here's what can be found around the lines where you're having an issue (the line numbers differ from yours, but that's probably due to a version difference):
347 for k in auth_keys:
348 provider = AUTH_PROVIDERS.get(k.provider, None)
349
350 if provider is not None:
351 name = "%s: %s" % (provider.context.human_name, provider.context.readable_key(k))
352 else:
353 from forum.authentication.base import ConsumerTemplateContext
354 "unknown: %s" % ConsumerTemplateContext.readable_key(k)
355
356 auth_keys_list.append({
357 'name': name,
358 'id': k.id
359 })
Looks like at line 354, we should have name = "unknown: %s" % ConsumerTemplateContext.readable_key(k), but someone forgot that name =.
I can't be 100% sure about this, as I am not really knowledgeable in osqa, but this statement doesn't do anything otherwise if we leave it like it is. Additionally, your bug is 100% reproductible provided you can identify why k.provider isn't in AUTH_PROVIDERS, which I guess has to be pretty uncommon.
You might want to file a bug at osqa's bug tracker. To solve your issue in the shorter term, you could:
provider is None. (Apparently, the issue caused by there being and auth_key for the current user that doesn't correspond to any of AUTH_PROVIDERS).
