--- Comment #7 from Andrey <ahippo at yandex.com> ---
Still broken in 7.8p1 on Linux with IPv6 enabled in the kernel
(CONFIG_IPV6=y), but disabled (/proc/sys/net/ipv6/conf/lo/disable_ipv6)
at runtime.

Specifying "AddressFamily inet" fixes the problem.
Toggling "disable_ipv6" back also "fixes" the problem.

Setting "X11UseLocalhost no" also workarounds the problem in a more
dangerous way.
