[Message part 1 (text/plain, inline)]

Hello Emacs Maintainers,
Emacs 24 is great, but using openwith version 0.8f, downloaded from
http://web.student.tuwien.ac.at/~e0225855/misc/openwith.el
I get an error when opening a pdf file in dired.

See my Stackoverflow question for more info:
http://stackoverflow.com/questions/8566045/emacs-lisp-problems-with-filename-string-on-win7

Recipe:
emacs -Q
C-x d ~/.emacs.d/site-lisp/
L (with point on openwith.el)
C-x d ~/.emacs.d/org/projects/sandbox/ ;just an arbitrary pdf file
f (with point on 2test.pdf)

With M-x toggle-debug-on-error I get:
Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  file-truename(nil)
  find-file-noselect-1(#<buffer 2test.pdf<2>>
"~/.emacs.d/org/projects/sandbox/2test.pdf" nil nil
"~/.emacs.d/org/projects/sandbox/2test.pdf" ((3328 6 . 23491) (16087 .
35227)))
  find-file-noselect("c:/Users/tj2/.emacs.d/org/projects/sandbox/2test.pdf"
nil nil nil)
  find-file("c:/Users/tj2/.emacs.d/org/projects/sandbox/2test.pdf")
  dired-find-file()
  call-interactively(dired-find-file nil nil)

Cheers
Thorsten

PS
I will be offline for 2 weeks from now

I think it's a bug in openwith.el: it doesn't set buffer-file-name,
which find-file-noselect-1 needs.
