It works on my environment without crash.

Camera: Logitech C910

$ hg id -i

$ env | grep -e XDG_CURRENT_DESKTOP -e DISPLAY
WAYLAND_DISPLAY=wayland-0

But the indicator isn't shown yet:

Gdk-Message: 15:59:45.814: Window 0x7f599f102500 is a temporary window without parent, application will not be able to position it on screen.

It works fine for me with trunk & Fedora 28, even the indicator is shown.

Attachment: Bug 1431399 - [Wayland] Render eWindowType_child as a toplevel window on Wayland, r=ashie

eWindowType_child window (a window defined by GdkWindow only) is not supported on Wayland
as we need moz_container to provide wl_surface to draw into.

As a workaroud create a regular toplevel window instead of child on Wayland to enable
rendering and window manipulation.
