When I have found a bug but don't know which package it's in, it would be useful if the "Report a bug" wizard could point me to related packages.
As an example; for me, the live CD complex is problematic. I have learned (the hard way, we might add) what "ubiquity" and "casper" mean but now I found myself wondering again where to file a wish for an additional package to include in the Live CD. Looking at Ubiquity and Casper bugs, I see no bug reports which resemble mine, but I have no idea where to go next.
(I ended up reporting bug #217138 against Casper, hoping that somebody who knows this stuff better will reassign to the right package, unless of course Casper was the right package for this bug after all.)
The "Depends": and "Suggests": fields are -- in this case, at least -- not sufficient for finding related packages. They also by themselves don't include any description of the packages, so for example, if I am not familiar with "dmsetup" (in the Depends: of casper) I will need to look it up separately.
I can totally understand the trouble of trying to determine the right package to file a bug against.
However, this bug's description is currently a bit vague as far as how to address this problem. Could you elaborate a bit more on how you envision it should work? Perhaps that would clear things up conceptually.
