[PyQt] Use qRegisterMetaType()

[AON LAZIO]

Hi, guys.
  When I tried to do connection like this

self.connect(a,SIGNAL('output(QVariant)', self.update)

I got this message

QObject::connect: Cannot queue arguments of type 'QVariant'
(Make sure 'QVariant' is registered using qRegisterMetaType().)

I found out the searh to 'qRegisterMetaType' led me to QMetaType Class
but I got no clue to properly use it
Anybody know how to do this?
Thanks
