Hi G,
hi hit this one also, you needs some "@pyqtSignature" magic

see par 3.7
http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html#connecting-signals-and-slots

my problem was calling a ok button method twice:
without the "@pyqtSignature" magic, the on_btnOk_clicked will be called 
two times: one clicked() and one clicked(bool checked)

@pyqtSignature("on_btnBrowse_clicked()")
def on_btnBrowse_clicked(self):
   print 'bla'

hope this helps
