I can reproduce the behaviour, it appears everytime something is dragged. This might be a feature, it is possible to drag an Directory from Desktop to the Trashbin (in the launcher). Nevertheless there is no action possible with a dragged text in the launcher. This action shout be implemented or the behaviour shout be changed.
