[Evolution] Evolution Freezing and IPv6

["my-no-spam outlook com" <my-no-spam outlook com>]

I've noticed that if I enable IPv6, evolution just hangs opening my
mail and sometimes just freezes if left open. If I disable IPv6, the
application performs like a rock star. Any ideas where I might start
troubleshooting this? I have watched the network connectivity and, from
what I see, it appears that only one of the three connections to the
remote server actually gets established.
