YMMV -- my experience with ABRT is that it provides little useful
information by itself and that the reported bugs rarely have reporters
interested in following-up with more information. Plus, it does a
terrible job correlating new bug reports with existing bug reports.
I would vote against cluttering bugzilla.kernel.org with nearly
useless automated bug reports...
