It would have the same advantage as distributed source control: it's distributed. It works offline, meaning I can add bug reports, comments, change them and so on and so forth while being offline. Or one could work on the reports and publish a cleaned up state, without all the noise he might have generated during triage. That's two cases where being distributed would help. Also, most of the current distributed bug tracker efforts tie into a distributed VCS, which has the added advantage of the entire issue database coming coupled with the code: one doesn't have to visit yet another web application, doesn't have to figure out where the original bugtracker is, and so on and so forth.
