--- Comment #15 from Mike Stump <mikestump at comcast dot net> 2011-03-21 18:53:12 UTC --- I'd trust the person doing the work. :-) They usually have more state on exactly what problem they are fixing and if the work for any one bug covers the problems in other bug reports completely or partially. I prefer that as enough work is put in to fix one bug report, that that bug report is then marked as fixed, and other the other bug reports that are completely solved by it are then marked as dup of that bug.
