Tmux crash when I press ESC in insert mode, how to fix that?

Question

I use tmux 1.7 and iTerm2.

When i run Vim and go to Insert mode and then press Esc key my tmux session crashes with following message:

[lost server]
%

This have to be problem with tmux, because when I run Vim wihout vimrc it happend too. Also I cleared tmux.conf file but wihout success.

How to handle with that error.
