Change title outside of constructor in Popup results in changed font

[mathias]

Just noticed this strange behaviour. If i pass the title in the super(title), it is left-aligned and with the default/expected font. But if i do it a bit later, using the setTitle-method, the text becomes centered and with a different font.

Any idea what causes this? Can i do something about it. I don't change any layout-parameters of the Popup.
