How is lisp code run with eval-buffer different from lisp code called by
a function with respect to permissions?  I mean, how can the

  (dbus-call-method ...)

above work, but calling

  (defun TeX-evince-sync-view ()
    (dbus-call-method ...))


Thomas, here's something you could try as well.  Inside the auctex
buffer (the TeX-master file, if you have a multi-file doc), do

  M-: (let ((file (file-name-nondirectory

Does that work?
Now, this actually works - sort of. At least it brings up evince showing the document. However, it also opens a buffer, *Backtrace* in Emacs, saying:
Debugger entered--Lisp error: (dbus-error "Message did not receive a reply (timeout by message bus)")
  dbus-call-method(:session "org.gnome.evince.Daemon" "/org/gnome/evince/Daemon" "org.gnome.evince.Daemon" "FindDocument" "file:///home/tha/sparsig-private/kursus/p%c3%a6dagogikum2011-2013/modul5/module5.pdf" t)
  (let ((file (file-name-nondirectory (file-name-sans-extension (buffer-file-name))))) (TeX-evince-sync-view))
  eval((let ((file (file-name-nondirectory (file-name-sans-extension (buffer-file-name))))) (TeX-evince-sync-view)) nil)
  eval-_expression_((let ((file (file-name-nondirectory (file-name-sans-extension (buffer-file-name))))) (TeX-evince-sync-view)) nil)
  call-interactively(eval-_expression_ nil nil)
Furthermore, evince blocks Emacs while open. I cannot interact with Emacs until I close the evince window again.
