When running Qt4 applications (there's still quite a few of them), they
use a very tiny font for their UI. When I run the "qtconfig" tool to
configure the font size, it works initially. However, on the next login,
KDE overwrites my ~/.config/Trolltech.conf file and puts this in it:
So all Qt4 apps use a 9pt font again, which for me is tiny.
I cannot find a spot in System Settings where that "9" comes from though.
