Ok, that's the info I was looking for :)..
Looking at that group, should I understand you have only one destination
in there, while having the "use_default" on ? This makes a bit of none
sense - the group has only the default destination (to be used in case
of failure), but no regular destination ??
Anyhow, there is a bug there, but I want to understand your setting, to
be sure that the fix will be the right one ;)
Thanks and regards,
Bogdan
