This was caused by a change in firewall settings format.

dom0# cd /var/lib/qubes/appvms/
dom0# cp problemvm/firewall.xml problemvm/firewall-orig.xml
dom0# cp goodvm/firewall.xml problemvm/firewall.xml

Now restart the host machine.

This should fix the problem.
You can then manually replace the firewall rules.
