I can't really help you, neither on my machine or on any clean install I happen
to have this conflict.
You can try to really update your machine and force remove everything that
should not be there:
zypper dup --allow-vendor-change
zypper rm $(zypper packages --orphaned --unneeded | awk -F'|' '/^i/ {print
$3}')
zypper dup --allow-vendor-change
