OK.  I don't know which commit introduced the problem.  Do you want
something like this?

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1196089
or
Fixes: https://www.redhat.com/archives/dm-devel/2015-June/msg00111.html

I know some folks don't like mailing list archive links in the commit
messages.

Cheers,
Jeff
