I tried to look at an RC bug this evening: bug #502657 on netmaze. It looked so easy - a segmentation fault, a backtrace... no. The package doesn't even build on sid, doesn't support the 'nostrip' option, and hasn't had an upload for two years. When you get past those stumbling blocks, it's a 64-bit compatibility problem that would probably need quite a large patch.
So, in the end, I've increased the RC bug count by one this evening, in suggesting to the maintainer that netmaze should not be released with lenny.
I tried.
