It would be useful to have a #BugReporting platform that works independently of individual projects.
The interface would walk you through describing exactly what's bugging you, and help you tag in all the software projects that might be implicated. A triage process would then figure out which piece of software is actually causing the bug. The issue thread for the bug can then be cloned to the issue tracker of that project.
This would be much easier to do with #ForgeFederation.
