Description of problem:
Today I opened up https://bugzilla.redhat.com/show_bug.cgi?id=708406. In the opening comment for that bug, I referenced the term "RHEL-6". For some reason Bugzilla decided to take that reference and make an automatic link from it to https://issues.jboss.org/browse/RHEL-6, which doesn't exist. The reference is totally bogus; it should either link somewhere into http://bugzilla.redhat.com, or just not do the automatic linking at all.
Ha! You can actually just see the problem in this bug directly, since I referenced RHEL-6 here :).
