Open a second window in PyQt

Question

I\'m trying to use pyqt to show a custom QDialog window when a button on a QMainWindow is clicked. I keep getting the following error:

$ python main.py 
DEBUG:

Ui_Dialog should inherent from QtGui.QDialog, not object.

class Ui_Dialog(QtGui.QDialog):
    def __init__(self, dbConnection):
        QtGui.QDialog.__init__(self)
        global c
        c = dbConnection
