Server Error (500) starting with 02f8c2818bfd

[Aaron Conole]

Commit 02f8c2818bfd ("htdocs: Add clipboard.js") has caused my patchwork
instance to start throwing server error.  I am not sure which logs to
look at (because /var/log/httpd/error_log doesn't seem to get updated
right now).

I'm using Firefox 53.0.3 to access the server.

Server is running:
 httpd-2.4.6-45.el7.centos.4.x86_64, Django (1.11.2), mod-wsgi (4.5.15)

Let me know what I can do to help debug.
