Thanks! I still need to optimize things, as refreshing the GUI slows down 
the shooting process on the Nokia (I have the choice of letting the GUI be 
out-of-sync, but the process be real time, or having the GUI synchronized, 
by using the Qt.BlockingQueuedConnection flag on signal connections, but 
the process not real-time anymore).

I'll have a look at this tool.
