Oops, I was being too hasty. On more careful inspection (and a cup of coffee)
both objects you're connecting are in fact QMenu.
Maybe you can try with "old-style" connecting:
from PySide.QtCore import QObject, SIGNAL
...
QObject.connect(
self.m1, SIGNAL( 'aboutToShow()' ), self.aboutToShowHandler)
QObject.connect(
self.m2, SIGNAL( 'aboutToShow()' ), self.aboutToShowHandler)
