Package: kdenlive
Version: 18.08.1-1
Severity: normal

Dear Maintainer,

On an update Debian sid with Gnome 3 with wayland graphics,
exiting full screen preview in kdenlive manages to kill the whole
Gnome session.

This does not happen if Gnome is started with Xorg graphics stack.

Steps to reproduce:

 * login to Gnome3 with wayland
 * start kdenlive with and empty project
 * double click with mouse to project monitor to start full screen
   preview
 * press ESC key or double click with mouse to exit the preview.

After this the whole gnome session is killed and user is greeted by
gdm3 for login. Expectation is that the full screen mode is exited and
kdelive window displayed.

systemd journal has only these hints of the event:

Actually, Gnome doesn't use weston as wayland compositor but mutter.

Since this bug report is quite old and nobody else complained, I am closing it.
Please re-open if it still happens.

Best regards,
Dylan
