Currently, it seems that

(bounds-of-thing-at-point 'existing-filename) ;=> nil

even if at the same time.

(thing-at-point 'existing-filename) ;=> non-nil

To reproduce in emacs -Q, write some existing filename into *scratch*
and then using M-: evaluate the above expressions.

I propose a simple fix in the patch below.
