This is a 2 part bugreport. First, the up2date which came with limbo2 didn't
calculate the dependencies correctly when i tried to update some packages just
now. Since i've got gstreamer-0.4.0 installed and that requires the rc3 version
of vorbis-tools/libogg/libvorbis i specifically deselected those packages in the
list.

After calculating the dependencies it apparently ignored what i did and used
those newer packages anyway, resulting in a conflict where gstreamer will not
work with the 1.0 packages of ogg vorbis.

Thinking this might be fixed in a newer version of up2date (rawhide), i
downloaded & updated my up2date packages. I downloaded & installed the following
packages:
up2date-2.9.33-7.x.9.i386.rpm
up2date-gnome-2.9.33-7.x.9.i386.rpm
python-optik-1.3-2.noarch.rpm

That last one is required by up2date.

After succesfully updating the packages, i tried to run up2date again without
success. It immediately returns with an error:

[root@anduril Downloads]# up2date
creating readOnlyTransaction
Traceback (most recent call last):
  File "/usr/sbin/up2date", line 18, in ?

    ts = transaction.initReadOnlyTransaction()
  File "/usr/share/rhn/up2date_client/transaction.py", line 25, in
initReadOnlyTransaction
    read_ts.setVerifySigFlags(8)

Perhaps i need to update another (python?) dependency, but i have no idea which one.
