QAction not triggering a signal/slot not getting called in PyQt4

ActionObject used to hold on to the callback for a QAction:


class ActionObject(object):
  def __init__(self, owner, command):
    action = QtGui.QAction(command.name, owner)
    self.action = action
    self.command = command
    action.setShortcut(command.shortcut)
    action.setStatusTip(command.name)
    QtCore.QObject.connect(action, QtCore.SIGNAL('triggered()'), self.triggered)
  def triggered(self):
    print("got triggered " + self.command.id + " " + repr(checked))


Command object used to hold on to miscellaneous command information, and manufacture actions:


class Command(object):
  def __init__(self, menu, name, prio, id, shortcut=None, icon=None):
    self.menu = menu
    self.name = name
    self.prio = prio
    self.id = id
    self.shortcut = shortcut
    self.icon = icon
  def makeAction(self, owner):
    ao = ActionObject(owner, self)
    return ao.action


Function that populates a menu bar given a list of command objects:


menubar = None

def build(frame, commands):
  global menubar
  menubar = frame.menuBar()
  for i in ['File', 'Edit', 'Project', 'View', 'Other']:
    menu = menubar.addMenu(i)
    last = 0
    for j in commands:
      if j.menu == i:
        if int(j.prio) > last+1:
          menu.addSeparator()
        last = int(j.prio)
        menu.addAction(j.makeAction(frame))


"frame" is a QMainWindow, and "commands" is a list of Command objects.

Yes, I know that the menus get created, what with them actually showing up in the window and whatnot...
