Public bug reported:

Hi there!

I perfectly know that Nova is a required component for Horizon, however,
for all pages, if only Keystone is installed (ie: Nova isn't), there's
only a RED error message on the top-right of the web page, saying that
compute isn't installed. However, going to /project/access_and_security/
generates a python dump:

It'd be nice to have this page error out in a more nicer way. As Mathias
pointed out on IRC, some people are using Horizon for a Swift only
install.

It's fine to have this bug having a lower type of priority, however,
it'd be too bad to just forget about it. :)
