Searching anything causes a HTTP 500 error

[srinidhibs]

Steps to reproduce:

• Head over to https://hackweek.suse.com
• Enter a string - e.g., "yast" or "y2profiler" - in the search box and hit the Enter key.
• You will receive a 500 error message.

Additional information:

I don't know if this is related or not, but when I followed a link to a HackWeek project from a Google search - https://hackweek.suse.com/19/projects/speed-up-installation - even then, I received a HTTP 500 error.

Sidebar:
I'm unable to login to hackweek.suse.com hence, I cannot confirm whether the problem is seen only when I am not logged in.

I tested that it also happens when logged in.
