To reproduce,
   Visit a library file containing a `require' form, e.g.,
   "M-x find-library RET yow RET". Search for a `require' form and
   position point on its the opening left parenthesis.  Invoke
   `find-library' interactively with "M-x find-library RET".

   Instead of prompting for a library name, Emacs displays the error message
   `Scan error: "Unbalanced parentheses", 1222, 1'.

   The error is in the interactive form of `find-library' in `find-func.el'.
   If point is over the opening left-paren of the `require' form then
   `function-called-at-point' returns `require', whereupon `backward-up-list'
   fails because point is not in a list.

Suggestions (for what they're worth :)
   (a) Handle this special case in the `find-library' interactive form.
   (b) Modify `function-called-at-point' to do what its docstring says.
   (c) In the `find-function' interactive form, use `condtition-case'
       to detect errors in computing the default.
