Hi

when I insert the following source block

#+begin_src sh :exports results :var
ver=(vc-working-revision(buffer-file-name))
  echo Revision $ver
#+end_src

into a svn (probably other VCs as well) registered file and execute it
via C-c C-c, it gives me the revision:

#+begin_src sh :exports results :var
ver=(vc-working-revision(buffer-file-name))
  echo Revision $ver
#+end_src

#+results:
: Revision 191

So when exporting, I would expect that it also prints "Revision 191",
but I get an error:

vc-file-getprop: Wrong type argument: stringp, nil

Tangling the file with :var ver=(vc-working-revision(buffer-file-name))
as a header argument also works fine.

As the evaluation works, I assume that is a bug somewhere?

Cheers,

Rainer
