zypper

Just a little tip in case there is anybody out there with the same problem...
:-)

This morning i wanted to install some updates with 'zypper up'. That usually works without any problems!
But... Today it would go up to 100% installing the first package and then just hang forever. It didn't use any CPU, so it took me a while to even notice! Some investigation showed it was the rpm process not doing anything that zypper waited for.
rpm --rebuilddb didn't help, neither did removing zypper's cache...
