GNOME Bugzilla – Bug 693066
GTK notification code attempts to create an X notification Window with the Wayland backend

This is the GDB output of bt full on nm-applet when trying to run it with the latest GTK git with GDK_BACKEND=wayland. http://pastebin.com/Geit9ia7 It seems that GTK itself is what's causing nm-applet to crash with the Wayland backend by trying to create an X window for the notification.
Yeah, GtkStatusIcon needs to be fixed for a multi-backend world
Fixed with http://git.gnome.org/browse/gtk+/commit/?id=377997f7043e178d2d83daf585ee588966f0b1c4
