admins redirected to error page on login

[NedHenry]

This is low priority because it does not affect any public view of the site, but after I log in I am getting redirected to /admin/users/undefined instead of the page I was originally looking for. I will investigate this when I get a chance.

Update: this bug seems to only appear in firefox. I do not see this error in Chrome or Safari.
