Version: 24.1

Thanks for the report. I see this in Emacs 23.3, but not the current
trunk, so it looks like this has been fixed.

	global-whitespace-mode does not survive in buffers changing major mode

When global-whitespace-mode is enabled, all existing and new buffers get
whitespace highlighting, but the highlighting goes away in any buffer
whose major mode is later changed.  You can see this, for example, with
  SPC SPC <return> M-x global-whitespace-mode M-x c-mode

I think the fix is to define global-whitespace-mode with
define-globalized-minor-mode, instead of trying to simulate it with
find-file-hook.
