cannot redirect to nil Rails devise

Rails 3.2.16

Devise 2.2.4

Upon authenticating with basecamp using devise I get an error. This error is intermittent, to fix without editing the code please try the site url again and it should work, if not clear your cookies and try again if you don't want to clear your cookies try using a private window and try again.

This is the error
