Sorry, this issue is still present after an update to gnome-shell 3.18.2.

With `GDK_BACKEND=x11 epiphany` I get the crasher after the extension is successfully updated/installed. With wayland GDK Backend (default under Gnome+Wayland) the plugin isn't even loaded.

Hm, that's unfortunate, thanks for testing....

We currently have no plans to support plugins under Wayland. Most interesting plugins could never run under Wayland anyway.
