Hehe, yes, I was just about to write you the same. My test build with this one
reverted lets me load the ruleset again.
Would you like to take this upstream? I was just about to file a report in
netfilter's bugzilla, but since you also worked on it as well, I don't mean to
interfere...
I'll try to further reduce my test ruleset to see what actually triggers this.
Thanks and regards,
Timo
