[Interest] Qt5.1.0 Blocking when new QQmlComponent

[sun.hw]

Hi guys,

    I  have an issue  to hide a quick item and show another. When I use new QQmlComponent( engine, qml_file_name, rootObject ), 
blocking happens sometimes. And most of the time it run well with the same qml_file_name . Why?
   Has anybody met such a problem?

   Kind regards,

   Albert Sun
