Just a guess, but review the @grant directives at the beginning of the script.
CODE
// @grant GM_getResourceText
// @grant GM_getResourceURL
// @grant GM_addStyle
Those are in the script; I added them as one of my fixes. Any other suggestions?
EDIT: And incidentally, line 472 in that script (which the error message above seems to refer to) is the fourth line in the Storage Items section:
CODE
var item = localStorage.getItem(key);
Dunno if that helps, but it can't really hurt....
