            Bug ID: 762258
           Summary: wayland: gtk3 apps segfault with

     GNOME version: ---

Summary:

When gtk3 apps are run with kwin s Wayland compistior, they segfauls at
startup. 

Downstream bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1298371

How to reproduce:

1. Run a kwin_wayland nested session:

   $ kwin_wayland --xwayland --windowed

2. Start any gtk3 based application

   $ gnome-calculator

Additional data:

kwin (at least the version found in Fedora 23) does not support xdg_shell
whereas gtk3 take it for granted.

segfault in wl_proxy_marshal_constructor() because the proxy is NULL.

Not much gtk+ can do really, but it should bail out more gracefully I guess...

Patch to follow.
