How about reputational points gained tied to the number of votes on the bug? This would both encourage coders to fix bugs that impact more people and encourage users to voice their opinion (vote on bugs) more often and more intelligently. Alternatively, the maintainer assigns a point value to each bug, and whoever fixes it gets those points, which is then used to rank contributors within that project (but not across projects because of bug valuation inconsistencies and differing values of the projects themselves).
