Well actually... a VLC object pointerc must never ever ever ever ever be 
passed to a Qt signal. This is prone to unsafe constructs. Qt signals are 
asynchronous, and hence cannot directly interoperate with VLC object 
reference counting.

Also, the input manager is a horrible pile of spaghettis, intertwining events 
*and* signals/slots, and using both function parameters and object properties 
for the same informations (look at inputChanged and setInput!!).
