html5 not working

[RudolfVonKrugstein]

When I try the sample demo or a simple test with

lime test html5

I get this error after the preloader:

Uncaught Cannot cast null to {
    __name__ : [ru,stablex,ui,widgets,Widget], 
    _X_USE_LEFT : 1, 
    _X_USE_LEFT_PERCENT : 2, 
    _X_USE_RIGHT : 3, 
    _X_USE_RIGHT_PERCENT : 4,

    _Y_USE_TOP_PERCENT : 6,

}
