We (graphviz upstream) are unable to reproduce this problem on our build of graphviz-2.30 on ubuntu12.
For us, running: $ echo "digraph G { foo; }" |dotty - renders an ellipse containing the label "foo"
If this problem still occurs for you with graphviz-2.30, please send config.log from the build. It sounds like there may be a problem resolving fonts?
