[fprint] Libfprint and Qt

[Nicholas Shatokhin]

I use libfprint's async API in qt class. I see example code in  
fprint_demo. Now, I use GTK event loop (my source:  
http://ubuntuone.com/p/vAw/). How can I use Qt event loop? And I have one  
problem on my AES 1610: if finger stop on scanner for a long time, program  
crashes. I don't see it in fprint_demo, but my program has this problem.  
Can anybody repeat this error?

Best regards,
Nick.
