Did you actually add some bulk actions to the bug tracker view? I don't use bug-tracker personally so I'm not keen on installing it and filling it with data manually to add the bulk actions.
Bulk actions I have been thinking of:
A) Assign bugs to myself
B) Close bugs
C) Unassign myself from bugs
Furthemore, some of the filters do not seem to work properly. At least when I try to filter by package I don't get the package bugs only.
