The Ubuntu font that is bundled with Natty in Beta 1 of Kubuntu renders
in bold in KDE and QT apps when using either "none" or "slight" as
hinting style, while "medium" or "full" correctly renders the font in
regular weight. This applies both to sub-pixel rendering and regular
anti-aliasing.

The issue seems to have happened around the Beta 1 mark, as replacing
/usr/share/fonts/ with the one from a previous build (not sure which
exactly, but pre-beta anyway) fixes the problem.

GTK rendering is unaffected (Firefox renders the Ubuntu font in regular
weight).
