FC5t3 - rpm -e hangs up

["Jan Andrejkovic" <jandrejkovic gmail com>]

Hello,

I have upgraded FC4 to FC5t3. I had some xen problems therefore I have decided to reinstall xen packages.
But when I try 
rpm -e kernel-xen-hypervisor-devel or rpm -e kernel-xen-guest-devel rpm hangs up and eats almost 100% cpu for long time.
I need to use kill -9 to stop it.

I have tried to do 
rm -f /var/lib/rpm/__db*
and
rpm --rebuilddb
but nothing helped after those commands - it hangs again.

I have also tried rpm -e --justdb but it did not help either.

Initially it was "yum remove" which hanged first. But as far as I know it uses rpm therefore I report this as rpm problem.

Does anybody have the same problem or can anybody tell me some workaround how I can remove those packages manually and possibly rebuild database without them?

Thank you very much,

Jan
