I'm running Sage 6.4.1 on OS X (Yosemite). Creating a directed graph with n vertices (for any n that I tried) returned +Infinity. EG:
sage: digraphs.Path(10).diameter()
+Infinity
or even
sage: digraphs.ButterflyGraph(5).diameter()
+Infinity
However, both of these Path and Butterfly graphs are finite, connected, directed acyclic graphs so their diameter should always be finite.
