Everything goes right, and exactly that is the thing that makes me curious. 
The call comes to emitSignal() in the class EmitSignal, the loop goes right 
and _qobj->activate() is called. The signal is emitted, but all arguments are 
0.
If I print the contents of, e.g.  s_int, I get a result, so the arguments are 
passed to the class. But it seems as they are not correctly "processed" by 
activate().

I'll compare the QtRuby code and the Qyoto code, maybe I'll find a difference 
which is quite self-explaining.
