example

In the main window area of the Yast partitioner where the graphs, installation
summary, settings options, etc. should be displayed, there is only centered
text saying "devicegraph" or "summary" or "settings" instead.  This obviously
deviates from the expected behavior, even when a particular node has no
information to display, i. e. no installation summary because no changes have
been made.  An example is attached.  This was a vanilla, rarely used (read: not
up-to-date by a couple weeks), Tumbleweed installation up until I converted it
to Leap 15 yesterday, so maybe it just missed a couple new libstorage-ng
packages, like libstorage-ng-utils or one of the plugins for example.  However,
I wasn't sure about this theory as the ones currently installed,
libstorage-ng-lang libstorage-ng-ruby and libstorage-ng1, looked like they
upgraded directly from libstorage7 and libstorage-ruby in the zypper logs (and
this behavior was obviously not present with those packages).  The hard drive
uses GPT in multi-boot with several other systems, and the root filesystem is
xfs.
