Indeed i just narrowed it down just before i saw the announcement.
But i also thought it was a known problem:
http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=utf-8&selm=agtvks%246cq%241%40venus.btinternet.com

Thanks alot for taking interest.

First i tested various combinations of:
IMAP Servers: cyrus, courier, dovecot
OS: FreeBSD, Linux
Therefore i don't expect it to be problems of the respective implementations.

Though it seems to always lockup on the same message,
so make sure you use a folder with a bunch of messages.
If you still can't reproduce it i can happily give you
access to one of my servers.
There is a chance that the problem is located
in net/imap or one of its requires, but after
reading the above linked message i thought
i had found the source.

You can test it with this:
----8<----
#!/usr/bin/env ruby18
require "net/imap"


# CHANGE THIS TO YOUR ENVIROMENT
password    = "PASS"
user        = "NAME"
server      = "IMAPSERVER"

# CHANGE THIS TO TEST true/false
usessl      = true

certs       = nil
verify      = false

if usessl then
  port = "993"
else
  port = "143"
end

p @imap = Net::IMAP.new(server, port, usessl, certs, verify)
p @imap.authenticate('CRAM-MD5', user, password)
p @imap.select("INBOX")
p @imap.status("INBOX",["MESSAGES"])

parts = ["RFC822.SIZE", "INTERNALDATE"]
p @imap.fetch(1..-1, parts)
