           Summary: Weston crash when weston-desktop-shell and
                    weston-keyboard missing
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: ppaalanen at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 1.5.0
         Component: weston
           Product: Wayland

If weston cannot find both weston-desktop-shell and weston-keyboard, it will
crash as below. In my tests, I could not reproduce the crash if only one of
them was missing.
