The default plasma-desktop configuration causes plasma-desktop to crash

Binary package hint: kdebase-workspace

The default plasma-desktop configuration causes plasma-desktop to crash. It is uncertain whether or not it is an upstream bug, as we do patch the default widget layout. The backtrace seems to indicate a crash calculating the geometric constraints for the System Tray Plasma widget.
