Well if it's there, it's meant to work.. and if it's not, it's either a bug or I'm doing something wrong… I hope there are others who can test/confirm this.
Update:
OK, did a fresh clean install.. what I had said earlier may have been inaccurate, i think there needs to be a rule for each queue else something goes frenzy.. I removed all the queues to start have my own rules, doing further testing now to confirm.
Update 2:
Further confirmations required, as it is right now, every queue must have at least a pair of properly (confirm again please) written rules.
To test, I deleted all rules, got the errors. I added manually following the same format. The errors disappeared.
Note to developers:
The Apply Changes + Save can be a little misleading. Some sections after making changes you get the Apply changes box. (example, adding a queue). In many sections, we get this, so I have grown accustomed to pressing apply changes once I'm satisfied with them. However, when deleting rules, I don't get this "Apply changes" button, and since I'm already accustomed to it, I sometimes completely forget the need to press "save". Well, rather trivial, but i thought worth noting.
