I have seen the same messages during the work on my patch. They appeared
when moving a docked widget into a new position because the widgets
become floating and therefore normal windows during that. The solution
was to check if a widget is floating before setting the focus in the
handlers of the visibilityChanged signal.

At the moment I have no idea why this happens at start up. Are your
widgets floating or docked at startup and do the messages also appear
later when you are moving the widgets?
