I use Tmux version **1.9**. To push tmux's clipboard to my **X** clipboard I have such a string in `tmux.conf`:

 bind C-c run "tmux save-buffer - | xclip -i -sel clipboard"

The problem is that after pressing `C-b C-c` content of tmux's buffer goes to the **X** clipboard, but also all the key bindings stop working. 
I can't create a new window, pane, etc.

Has anyone faced such a problem?
