Sebastian,

we have a widget called Sash, that is derived from 
qx.ui.splitpane.SplitPane. This widget causes the error when he user 
starts to drag the divider.
But I guess there is more since the with more widgets, error occurs 
already before any user-interaction has taken place.

Cheers,
Rüdiger
