We should be able to easily split one bug report into multiple reports (for cases where one bug has multiple causes, or the reporter incorrectly perceived multiple bugs as a single bug) while keeping history of the case. And vice versa, for when a single bug is reported multiple times. Most bug trackers just let you resolve things as duplicates, which is kinda half-assed.
