Right now, the crash reports for this case never even make it to Launchpad,
so the question is somewhat moot.  However, assuming we could determine
which version it came from, and send that information to Launchpad, I know
of no reason the retracer couldn't be made to work.  It already checks the
versions and tries to install the matching debug symbols.

Your idea seemed to be aimed at allowing multiple versions of debug symbols
on the system, by using different paths.  The retracer just selects the
corresponding .deb for the particular crash it is working with, and doesn't
need more than one.
