Uh, that's strange. That's exactly what TeX-evince-sync-view does.

Hm, so TeX-evince-sync-view is called, doesn't error, and still does
nothing. Honestly, I have no clue how that can happen. Could you
please do `C-h f TeX-evince-sync-view RET' which shows the docs of the
function. It should look like
,----[ C-h f TeX-evince-sync-view RET ]

Focus the focused page/paragraph in Evince with the position
of point in emacs by using Evince's DBUS API. Used by default
for the Evince viewer entry in `TeX-view-program-list-builtin' if

Notice the difference, "compiled Lisp". Does that make a difference
here?
There, the `tex.el' is a link. Hitting RET on it brings you to the
definition of the function. It should look like
--8<---------------cut here---------------start------------->8---
(defun TeX-evince-sync-view ()
"Focus the focused page/paragraph in Evince with the position
of point in emacs by using Evince's DBUS API. Used by default
for the Evince viewer entry in `TeX-view-program-list-builtin' if
the requirements are met."
(require 'url-util)
(let* ((uri (concat "file://" (let ((url-unreserved-chars (cons ?/ url-unreserved-chars)))
(url-hexify-string
(expand-file-name
(concat file "." (TeX-output-extension)))))))
(owner (dbus-call-method

Now set point somewhere in the function and do `M-x edebug-defun'. Now
go to some tex buffer and try the View command with TeX-evince-sync-view
again. Now the function definition should pop up again, and you can
single-step through the function by repeatedly pressing `n' where the
_expression_ values are also printed in *Messages*.
I have tried debugging now. I execute `M-x edebug-defun' in the
function definition as you specify. This causes the following output
in the *Messages* buffer:
Edebug: TeX-evince-sync-view
TeX-evince-sync-view
Unfortunately, that is all that happens. When I execute
TeX-evince-sync-view in a LaTeX buffer afterwards, nothing
happens...
Does that share some light?
Unfortunately not, but thanks for trying,
Thomas
