bsc#1205570 is not accessible, so I cannot comment about it, but the "fix"
breaks scripts the relies on the output of the command:
  zypper pt -i
a workaround is to use:
  zypper pt | grep ^i
I don't know if, by design, zypper pt -i should not work any more or not, but
if that's the case you should at least update the documentation.
