Well what we really want here is:

Try "debuginfo-install glibc" (or "debuginfo-install python" if they
are running gdb on that), but that requires some kind of integration
with rpm or yum.

Well yum is just following the deps, for instance for me check,
check-devel and gstreamer-devel are the top three installs ... which is
because gstreamer-debuginfo requires gstreamer-devel, which is obviously
required by rhythmbox.
I'd say it's likely that we have some unneeded deps. on some of the
-devel packages (maybe should be BuildRequires?) ... on the other hand
it's not something that'll affect normal[1] users.

[1] If you want to use gdb, you aren't normal .

What is the reason why any *-debuginfo package requires any binary package?

Sure it installs .debug files which are only partially usable (officially not
usable) without their binary counterparts. But still even this dependency is
currently not complete there, I am not aware which rule generates the current
dependencies but it seems as useless there; going to submit the patch.

Sounds like a job for PackageKit, look up the path to figure out which
packages we are missing and offer the user to install the missing debug
symbols.

/usr/lib/rpm/macros has a better definition that uses "AutoReqProv: 0".
redhat-rpm-config should change to match (or better, change not to
duplicate the details). (The only intended difference is "debug" vs
"debuginfo", and maybe rpm can change that too.)
