This seems to point at a regression in Gtk. >From what I understand GTK_IS_WIDGET should return FALSE if widget is NULL.
It's defined here: https://gitlab.gnome.org/GNOME/gtk/-/blob/main/gtk/gtkwidget.h? ref_type=heads#L46 It's a macro that calls G_TYPE_CHECK_INSTANCE_TYPE, which is defined here: https://gitlab.gnome.org/GNOME/glib/-/blob/main/gobject/gtype.h? ref_type=heads#L541 The comment above this definition states G_TYPE_CHECK_INSTANCE_TYPE should return FALSE if instance is NULL. So I'm rather surprised this use of GTK_IS_WIDGET crashes gnucash.
