Hello, Under tmux, emacs 24.4.50.1 (trunk), the mouse drag does not work anymore. (It used to work fine on emacs24.3) drag and drop pane separation: result in outputing escape charcters in buffer (ex: [<0;133;27m), error: Wrong type argument: number-or-marker-p, nil drag and select text in a buffer: `Wrong type argument: symbolp, "drag-mouse-1"' FYI: Didn't reproduce with empty configuration, but with my config (solirized theme), the drag and select selects the linum mode as well as the text.
