On certain server configurations, a user of Safari browser was unable to login or register for an account. The server logs contain this message:

Exception on /login/ [GET]

This could be related to this issue.

This happens only when running Dribdat on Python 3, and is related to string conversion (Unicode from octet).

Not sure why it only affects a specific browser, though.

Looks like this is a Python 3 compatibility issue with the bcrypt library.
