 I've never done it, and would not know whether the results I get are right 
 or wrong. So I prefer to leave things like that to people who are more 
 familiar with that than me, and rather concentrate on further searching 
 the database for reports.

 Try to find the maintainers of the code and ask them for their opinion, 
 possibly in private mail. Maybe that helps, I see too many bugs slipping 
 through the cracks. Otherwise you may also send the patch to the list, and 
 put a "Unreviewed patch" in the subject to indicate that this is a 
 long-pending matter.
