Having upgraded to the upstream latest 2.31.20130722.0446 from ppa:
gviz-adm/graphviz-dev, I still see the missing label problem with dotty.
Rendering with 'dot' (to png, svg, ps, etc.) has always worked fine for
me.
I have installed all of the Recommended: and Suggested: packages.
FTR, my font resolution while rendering to png matches yours, close enough:
===
$ echo "digraph G { foo; }" | dot -v -Tpng -o foo.png
