[Debian-ha-maintainers] Oops breaks resource failover in RHCS

[Fabio M. Di Nitto]

Please file a bug on bugzilla.redhat.com -> Fedora rawhide -> component
cluster. I´ll take care to reassign it to the correct maintainer.

Yes I understand you are running Debian, but we use RH bugzilla instance
for upstream, so just go ahead and add all the info in there.

thanks
Fabio
