On my configuration the wronly selected font leads to colour bleeding which makes the rendering very ugly.
This is the changelog entry from Debian's libqt3 version 3.3.7-2.
* debian/patches/61_fcfontmatch_fontwidth_fix.dpatch
Fix font matching with fontconfig. This resolves inconsistency with
determining font width (e.g. Dejavu Sans "Condensed" may get selected
instead of "Book" for Sans Serif font) for default fonts (Sans Serif,
Serif and Monospace). This bug is very important because it makes
default KDE fonts look ugly in most cases.
