Can I rotate a background image via script?

This trial crashes MoI:

var img = moi.view.getBackgroundImages().item(0);

var objectList = moi.geometryDatabase.createObjectList();
objectList.addObject( img );

var factory = moi.command.createFactory( "rotate" );
factory.setInput( 0, objectList );
factory.setInput( 1, img.frame );
factory.setInput( 2, 45 );
factory.setInput( 5, 'false' );
factory.commit();
