I just upgraded a bunch of packages in my debian sid box, and I'm seeing
this same behaviour in mythtv, as well.
According to the tracing I've done so far, myth is actually receiving
multiple KeyPressEvents from the qt3 main loop. Here's the bt:

I watched #6 QApplication::x11ProcessEvent and saw that it is being called
multiple times when keys are pressed (it should be called 2 (one press,
one release), but it's often called 4 or 6 times).
