I have been discussing this issue on the tmux mailing list as well. It might be of use to you. http://sourceforge.net/mailarchive/forum.php?thread_name=E4CC964B-F09E-4D2F-B96C-7E6D64207FEC%40gmail.com&forum_name=tmux-users

The tmux developer said of the problem:
> This program is using 1047h to switch to alternate screen mode which
> unless you are using a very old terminfo is not in the xterm entry, so
> it's probably a bad idea to rely on it working.

He made a patch for tmux to work with 1047h, but I haven't tried it out yet.
