This may be due to something I missed in your code. When you
connect the signal from the signal mapper to your class, you
need to specify the signal as a C++ signature as well:
self.connect(self.signalMapper, QtCore.SIGNAL(
"mapped(int)"),
self.deleteProductIngredient)
The second example should now work.
Looking at the first example, which uses SLOT() rather than specifying
a Python method, the following might be due to the way you call
connect, though it is surprising:

It looks like you should try something like this:
self.connect(w, QtCore.SIGNAL("stateChanged(int)"),
self.signalMapper,
QtCore.SLOT("map()"))
I can't understand why calling self.app.connect() would cause the
connection to be attempted between self.signalMapper and self.app.
Maybe someone on the PyQt/PyKDE mailing list would be able to
explain the behaviour you're seeing:
