Thank you.

This is my fault. I'll set up a new topic and will merge a slightly 
modified version (the "specific" message is missing in the WARN case) of 
your patch.
I think I reused the pattern from another policy which is likely to be 
broken the same way.
I'll try finding and fixing  that as well.
