I can reproduce this with a buffer containing an empty heading.
(Slashes should work fine.)

org-format-outline-path takes a list of strings for path elements.  It
handles an empty list fine, but helm-get-org-candidates-in-file is
passing it (nil).  I'll update org-format-outline-path to discard nil
path elements, but I should also probably submit a patch to helm to make
it ignore empty headers rather than passing a non-string list.

Thanks.
