Bug#1010547: libgtk-4-1: Applications hang with "gtk_widget_measure: assertion 'for_size >= -1' failed"

[Andreas Kloeckner]

Package: libgtk-4-1
Version: 4.6.2-2ak
Severity: normal
Tags: patch

Dear Maintainer,

A patch for:

https://gitlab.gnome.org/GNOME/gtk/-/issues/4517

was recently merged to the upstream Gtk 4.6 branch:

https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4670/

Among potentially numerous other applications, this affected
xdg-desktop-portal-gnome for me, because the window chooser dialog for
screen sharing incurred a hang with the message in the subject line
repeated ad infinitum.

By building my own gtk package (see the "2ak" versions below), I was
able to confirm that the patch in the MR addresses the issue. I think
it would be useful to release a patched version of Gtk4.

Thanks for your service maintaining Gtk4 for Debian!
Andreas
