Generally it works if you just make your best guess, and the bug
fixers will move it to the correct one.
We mortals don't really know which package is the source of a bug,
just which package it affects, so even if the package responsible
appears to be obvious, it still often won't be the right one. The
package in which you see the effects of the bug is usually a good
start.
It's more important that you can add details of variation of the
bug e.g. 'it doesn't happen if I start the program by typing the program
name in a terminal but I do see this warning:'. If you can use gdb and
generate a backtrace, it's better still.
