The sidebar's icons looks really bad, enlarged and blurred, when shown without the underlying text.
See included screenshot.
STEPS TO REPRODUCE
1. Right click on kontact's sidebar and change between sizes and with or without text
Without text, the icons appears at the wrong size and blurred.
The icons should maintain the same size and crispness even when disabling the text labels.

Laurent, do you know where the code in Kontact decides the icon sizes for the different sidebar view modes?
it seems to be here :iconsidepane.cpp in "class Delegate : public QStyledItemDelegate" paint() method
