+Subject: [PATCH] GladeGtkBox: fix glade_gtk_box_post_create
+
+Some widgets with contruct properties like GtkMessageDialog get
+rebuilt right after they are created on project loading so we need
+to check glade_project_is_loading() intead of GLADE_CREATE_LOAD
+and use the object ad the connect data to make sure it gets disconected
+if it was the object being rebuilt
+
+Fix issue #479 "Glade 3.36.0 segfaults when opening a file"
+
+CVE: CVE-2020-36774
+Upstream-Status: Backport [https://gitlab.gnome.org/GNOME/glade/-/commit/7acdd3c6f6934f47b8974ebc2190a59ea5d2ed17]
