I think this bug affects only emacs-cvs users. It did mine and I found the following fix for it at emacswiki.org: (defun color-theme-face-attr-construct (face frame) (if (atom face) (custom-face-attributes-get face frame) (if (and (consp face) (eq (car face) 'quote)) (custom-face-attributes-get (cadr face) frame) (custom-face-attributes-get (car face) frame)))))
Which emacs port? (app-editors/emacs or app-editors/emacs-cvs). Could you try starting emacs with --debug-init and post the backtrace here? It sounds like a return of the old easy-menu bug.
I'm using emacs-cvs but it's a color-theme bug; it has been fixed in color-theme cvs and the fix put up on emacswiki: http://www.emacswiki.org/cgi-bin/wiki/ColorTheme#toc6 With --debug-init (after commenting out the fix in my .emacs) nothing different happened. I guess --debug-init only deals with errors occurring strictly within the init file. When I started color-theme-select I got an *error message, as expected, but nothing else happened. I could trace the relevant functions and describe what happens and put the output here and figure out why the above code fixes it but is that really necessary? * face-attribute: Wrong type argument: symbolp, (font-latex-doctex-documentation-face font-lock-preprocessor-face)
version 6.6.0 was added to portage which should resolve this bug,
