I also made the proposition that you could steal somebodys points by
supplying a shorter/better/cleaner patch to the same problem. The
judge there should probably be the maintainer (but he won't get points
for doing so himself) because he has to life with the patch.

The metric should be simple and should not fluctuate too much with
small changes, like adding spaces or newlines.
Also some interaction with the maintainer could be added. He clould
give extra points for clean fixes or deduce points for stuff he has to

Think about a Bug Squashing Party but with rules, statistics and points.

If you have such an odd selection you might not get any bugs by lack
of bugs and thus no points. Does that sound fair?

Thats when you draw a joker.
Same with "merge". You might merge it with a bug someone closes. Easy
