I also have ahd issues with rpm database corruption, but I don't know
what caused it nor how to reproduce it. sometimes there is a segfault 
when running yum, which is certainly in the rpmlib, and I guess it is 
what screews things, and also sometimes rpm never finish.

What I do is

rm -f /var/lib/rpm/__db*
db_verify /var/lib/rpm/Packages
rpm --rebuilddb
