Have you seen ticket #3589? Would that be compatible with apport?
If so, would it fill your needs. You can already compile with
compile type profile and get an optimized build with debugging
symbols. A profile build stack trace isn't as good as a debug
build one for debugging, but it is often sufficient. It also has
the benefit of having symbols for libavcodec, libavutil, which in
my experience generate most of the difficult segfaults. The downside
of the profile builds is that they still take up a lot of memory,
the release-dbg patch should mostly address that issue (but there
is still a 7% bloat penalty.)
