Nope, it's a problem with OpenBSD's pf implementation in OpenBSD 3.1.
bugzilla.org's web host is using OpenBSD 3.1 (plus security patches) as
their firewall, and the bug in their window scaling implementation was
fixed in OpenBSD 3.3. Unfortunately, they didn't see fit to include it
in the security updates, so you actually have to upgrade the system to
pick it up. It'll get upgraded eventually, but because it's a whole OS
upgrade it'll probably be a month or two.
It only affects machines running Linux 2.6.8+ kernels on the client end
(which is why people are just now suddenly running into it).
In the meantime, you can work around it by doing this as root:
sysctl -w net.ipv4.tcp_default_win_scale=0
To make it permanent, you can add the following to your /etc/sysctl.conf
The best writeup of the situation I've seen so far is at
