Given that VNC does this as well, I traced the problem all the way back to getaddrinfo() behavior in libc. I believe this describes it: https://bugzilla.redhat.com/show_bug.cgi?id=721350
tl;dr: It ignores loopback when enumerating addresses per family. Workaround is to define the display as ::1, which works fine since there's a global v6 address on the box.
