The problem in Quanta is that I have a QTabWidget derivated class which holds 
the KToolBar derivated toolbars. The classes are derivated only to gain some 
extra functionality, like react to mouse events.
The buttons on the toolbars are actions plugged into them. The plugging is 
done in the MainWindow::createContainer(). Now the problem is that the 
resulting widget height will not be correct, and you will see only the Tabs 
of the QTabWidget, but not the buttons themselves. 
Now after the actions are plugged, there is some tests about the 
minimuSizeHint() of the KToolBar and according to the result the height of 
the KToolBar and QTabWidget is adjusted. The code (quanta.cpp; 
createContainer()) looks a bit strange, and I just found and fixed a bug in 
it, but it took me several days to find the best solution that works in all 
With r1.345 the minimumSizeHint().height() is 27, with 1.346 it is 16. My 
settings are 22x22 for toolbar icons, so I believe that a KToolBar should 
never return a value less than 22. 

So with the corrected Quanta code the toolbar buttons are only half visible 
with r1.346 and fully visible with r1.345.

The relevant codes are:
quanta.cpp: 1556 - 1572
toolbartabwidget.cpp & .h contains the KToolBar and QTabWidget derived
