One of the issues I find from time to time are packages dependencies problems related with PPA's due careless package maintainers. These problems are normally fixed changing one line (or several one lines) in the package, which needs to be addressed by the PPA maintainers.
Now, I know that if these problems happened with Ubuntu (I've already submitted a patch to that one), or Debian for what matters, packages I these would be threated as bug report, as they are bug reports. The problem with PPA's is, that they don't have bug trackers in LaunchPad (or at least is not so obvious) so you have to contact the maintainer of the PPA's so they can fix their stuff. Now here comes my problem, whenever I address (or answer) these problems they lose value once they are fixed, since nobody should have the same issue again (which happens with the bug reports).
So, are these issues really on the scope of the site. I really don't care anymore (through I would love the package maintainers re-read the Debian Maintainers Guide) since I try to answer them from the package maintainer perspective, but I want to know if I can spend my time answering them without problem.
