While working on Debian, I often don't realize how some important packages lack manpower to handle issues. Examples that touched me are 'apt' and 'perl'. As someone told many times, it would be good if someone with free time, especially newcomers to Debian, help triaging/reproducing bugs in the BTS, writing patches etc. This activity usually doesn't require helper to be a DD or DM, and will usually be more appreciated than preparing 11th web server or 30th window manager to Debian archive. Just ask maintainer(s). Also, you may want to read http://wiki.debian.org/HelpDebian to get the wider picture.

I tried to quickly find a table with Debian packages with highest bug rates over the Debian BTS, but failed, so I constructed my own one, with the help of UDD. This list contains BTS packages with number of bugs > 100 and is available here. The top ten:
