1. Describe what you would like us to do:
   Fix a problem causing Pagure to return 500 Internal Server Error for logged-in users sometimes.

This is affecting me and others in https://pagure.io/fedora-infrastructure/issue/12260 (but that issue is for something different, so I'm filing this). For me, I get a 500 any time I access pagure.io in Firefox, but it works in epiphany and when using curl. Looking on the server end, I found this in the logs:

I have edited the actual tokens for obvious reasons, you can see the real values in `/var/log/httpd/error_log` on pagure02 if you have access.

1. When do you need this to be done by? (YYYY/MM/DD)
   ASAP.
