Some more information:
I have an action pointer called "the_action", a function to paint a size 22 
icon and a function to paint a size 32 icon and the following code:

the_action->setIconSet(QIconSet(icon22(), icon32()));

This should be correct according to the documentation:

	"QIconSet::QIconSet(const QPixmap & smallPix, const QPixmap & largePix) 

	Creates an iconset which uses the pixmap smallPix for for displaying a
	small icon, and the pixmap largePix for displaying a large icon."

I have selected size 32 for toolbar icons. The icon returned by icon22 is 
actually displayed in the menu as expected. But guess what is displayed in 
the toolbar among the other size 32 icons? It is not a size 32 icon. It is  
the size 32 icon scaled down to size 22!
