Bug#929346: atril: Segmentation when launche atril on wayland on chromeos
Control: tags -1 patch
Dear Maintainer,
I am just looking at some random bug reports with crashes.
In this case I think atril is or was not prepared to run
in a wayland session.
Attached patch is based on some porting guide to wayland and
with that atril shows its main window. Nothing more was tested.
I tested with a current Buster VM too - there this crash was
not to observe. But, as far as I see, atril got no changes
in ev_application_open_window like in my patch.
Therefore maybe Gtk got a fix to avoid this?
Should this bug marked fixed for atril/1.20.3-1 ?
Or marked as closed as Buster does not show it?
Kind regards,
Bernhard
