Exceptions with UTF-8 OpenID URLs

[François Marier]

When the OpenID discovery fails with a "consumer.DiscoveryFailure", an error message is printed to the logs.

However, that error message causes an exception if the OpenID URL contains non-ASCII characters like this one:

  https://plus.google.com/Exämple

Here's the error from the Django logs (/account/483/redirect_openid/):

Traceback (most recent call last):

Here's another exception, this time when deleting a photo (/account/3789/delete_photo/):
