When closing a thunar window using the assigned shortcut key, thunar sometimes hangs. This happens with 4.15.0, and https://gitlab.xfce.org/xfce/thunar/-/commit/442461b1635ecc55e6a1268e3f2e1ebde968d633 seems to partly fix it (though I am not 100% sure it really does). I can however still reproduce the issue rather easily when running thunar --daemon, opening a few windows and then closing them rapidly using the shortcut key; holding down the shortcut key combination is enough to achieve this. It then spills the console with messages like the following: `(thunar:17804): Gtk-CRITICAL **: 23:48:04.072: gtk_accel_group_activate: assertion 'GTK_IS_ACCEL_GROUP (accel_group)' failed`
