That requires us to rebuild the entire distro to get the minidebuginfo
rpms. Its certainly doable, but some work. I can produce a patch to
rpm-build that does this, but I can't really do the rebuild stuff, that
would need help from someone on the build team.

I'm not proposing that we drop the existing backtraces with full debug
info, but (appart from the other places where backtraces are also
useful) I'd like it if ABRT could somehow catch all the cases where
people abort a bugreport because things are scary/slow/bad
network/whatever and at least report the low quality backtrace, which
should be very quick and require little work from the user.

I don't have a full design in mind, but I'm thinking that as soon as the
user acks that he wants to report the bug we would start by just
uploading the low quality backtrace, and *then* start retracing the bug
and show the user the backtrace with full data etc, asking them if its
ok to submit the data. That way we get at least *something* in all
crashes, and perfect reports for users that goes all the way.
