up2date -u gives a an error in up2date.solveDependencies

Hi all

The same error was already reported by Thornton Prime (I found it in
the archive), but without detailed logs (see end of message)

My current server (from 0.9.4 RPM) runs on a freshly update RH 7.1
machine. The up2date client is running an RH 7.1 out-of-the-box, but
with up2date package itsself updated to up2date-2.7.11-7.x.1

This is my first try at really doing some upgrades with
up2date. rhn_register and up2date -l work smoothly.

Any hints?

CU, Joe
