Yeah... Further up the inheritance chain KAction also connects to receiver.
The result is that the selected signal is fired off twice, resulting in very
weird reactions of the code.
One way to solve this is to connect to receiver if and only if receiver takes
an int, and in that case NOT pas receiver to parent's ctor.
More clean to me seems to not pass the receiver to the parent anyway and do
all the connecting in KListAction's ctor. Even then we need to detect whether
the passed receiver takes a parameter or not though.
Simon, any other ideas and/or opinions?
