Label Alignment in KDE4

It aligns labels to the top of lineedits, not middle (well, ideally it should 
be baseline, but let's not ask too much).

It's not a problem with the styles, but with the layout (particularly since 
layoutLabelAlignment doesn't seem to do anything), it's more visible with 
Oxygen, however, because it has wider bevels.
