Mm after updating the git panel to the new api, I'd still like to
reconsider this. I'll explain:

There are a couple of cases there you just want to show an error
dialog without having a transient widget (for example a plugin that
failed to start). you can simply do this:

xfce_dialog_show_error (gtk_widget_get_screen (GTK_WIDGET (plugin)), .....);

or when you show an error on a button action that failed:

xfce_dialog_show_error (button, ....) instead of
xfce_dialog_show_error (GTK_WINDOW (gtk_widget_get_toplevel (button)),

or you simply set a GtkWindow as parent. The last get_toplevel thing
is more convenient, but for the GdkScreen case you now pass NULL which
might result in a dialog showing up at the wrong location.
