I can reproduce this. Interestingly, it seems the busy state only
shows up if the script is started as "ProgName.start()". If started as
"engine.startProgram("TestProgram")" everything seems to work fine.

I'm not sure what the difference between these two calling styles is,
and it's not quite obvious to me from looking at TaskBrowser.cpp
yet...
