Package built, might not be published yet:
http://download.opensuse.org/repositories/home:/favogt:/branches:/openSUSE:/Leap:/42.3/standard/

Please verify that it fixes the issue.

It took a bit longer as plasma5-integration links the lib statically as well
and so it had to be rebuild with the right libqt5-qtbase. That was a PITA to
find out...

Also please do not report bugs related to the global menu upstream if they
aren't reproducable on the latest supported release, as those are likely
downstream issues.
