The problem seems to be these lines near the top of
widget-complete-file

(beg (save-excursion
                (skip-chars-backward "^ ")
                (point)))

Are there actually situations where files are listed in custom
variables with space seperators? Or is this code attempting to find
the beginning of the widget? If the latter, there must be a better way
to do that.
