Hi,

quite "easy" (I searched a long time, too):
KXMLGUIFactory::plugActionList() needs the DOM of your GUI;
thus, you have to call createGUI(..., true) before. If the second argument
would be false (the default), createGUI will delete the DOM for memory
saving after the GUI is created; plugActionList would fail (as you notice ;-)

Can somebody the drawback of the default value of the second argument
to the documentation of createGUI?

Cheers,
Josef
