           Summary: client crashes if it gets an invalid keymap from the
                    compositor
    Classification: Platform
           Product: gtk+
           Version: unspecified
        OS/Version: Mac OS
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: Backend: Wayland
        AssignedTo: gtk-bugs at gtk.org
        ReportedBy: carlosg at gnome.org

     GNOME version: ---


If the client is given a keymap string which produces compile errors,
xkb_keymap_new_from_string() returns NULL and the xkb_state creation crashes
when given a NULL keymap.

I'm attaching a patch that, in these situations, issue a warning and keep the
previous keymap/state around, since having instances of those is indispensable
for keyboard events, even if not fully correct.
