The bug is in your .emacs

C-h v window-system RET

Documentation:
Name of window system through which the selected frame is displayed.
The value is a symbol--for instance, `x' for X windows.
The value is nil if the selected frame is on a text-only-terminal.

When "emacs --daemon" starts there's no X frame.
