[kcrisman]

To release manager: this ticket has been resolved by #5448. The graph still looks terrible! But that would be a different ticket.

[jason]

This should be closed due to #5448

[mvngu]

based on Sage 4.1.2.alpha4

[mvngu]

This has been fixed in Sage 4.1.2.alpha4. Closing this ticket as fixed by #5448:

[mvngu@darkstar sage-4.1.2.alpha4]$ ./sage -br main
