[Wayland-bugs] [Bug 773274] [Wayland] Crash under gdk_wayland_window_attach_image()

[gtk+ (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=773274

--- Comment #7 from Jiri Eischmann <jiri at eischmann.cz> ---
I managed to reproduce the crash even with the quoted method of forwarding when
there was an attached file present in the original message. The quoted method
doesn't crash if you forward a message without an attachment.

I get the same error:
Gdk:ERROR:gdkwindow-wayland.c:742:gdk_wayland_window_attach_image: assertion
failed: (_gdk_wayland_is_shm_surface (impl->staging_cairo_surface))

No other error.

Backtrace:
