Bug 149560 – [GTK] Crash in WebCore::cairoSurfaceSetDeviceScale visiting extensions.gnome.org in Wayland

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: WebKitGTK

[Michael Catanzaro]

From the downstream report: "Every time I browse on extensions.gnome.org/local, epiphany crashes. Note that this happens with epiphany running in a Gnome+Wayland session. Browsing extensions.gnome.org/local with firefox (running under wayland, but with X backend) it works fine. Seems like the gnome-shell-extensions-plugin isn't ready for wayland…"

But in theory, the plugin should be disabled under Wayland. I haven't tested yet. Full backtrace downstream; truncated backtrace:

I think this is the same as #149561.
