This is an old issue, see, for example

http://lists.gnu.org/archive/html/emacs-devel/2000-11/msg00244.html
http://lists.gnu.org/archive/html/emacs-devel/2007-12/msg01194.html

`default-frame-alist' really shouldn't be customizable.

FWIW, this is a bug in `custom-theme-recalc-variable'.  Try erasing
customizations for `exec-path' or `completion-ignored-extensions'.
