ADDITIONAL INFORMATION
Git bisect suggests a79f80ed79ae2a1de379d1f31f4e0cbec05d83ce in
plasma-workspace as the cause. At a glance looks like a Qt bug to me but still
quite peculiar.

It appears the systray applet gets expanded (AppletInterface::setExpanded(true)
is called) on teardown which has it try to create a full rep and then blow up
somewhere.
