[PyKDE] Morning pain

[Vio]

Being a newbie can sometimes be quite a pain :(
Would someone be kind enough to tell me why:

self.connect( self.myListView,
SIGNAL("mouseButtonPressed ( int button, QListViewItem * item, const 
QPoint & pos, int c )"),
self.slot_processMouseClick)

and slot:

def slot_processMouseClick(self,button,item,pos,c):
    print button,item,pos,c

throws me:

RuntimeError: Signal has wrong argument types for slot


I've been hitting my head on this all morning, without much progress. 
Any hints beyound "RTFM" would be very much appreciated.
Cheers,
Vio
