It showed up in another template after modifying the icons_fanfic() to add some new items, but went away when I restarted Calibre.
EDIT: It hasn't recurred since, so I think it might've been a one-time glitch.

For completeness, the message means that you created a user-defined template function (in python) with a name that matches an existing function but with different code. The problem is detected when the function is registered -- made available to the template language. The change could happen any time before that. I don't know how to make the error happen.
