It's a bit strange that the C-c C-c is undefined message comes before
the error.  Possibly there has been an earlier error which already broke
the initialization of `TeX-latex-mode' in that buffer.

That's strange.

If that's reproducible, try toggling debug-on-error before visiting that
file so that we know where the error occurs exactly.

Yes, indeed.  There's a predicate `TeX-evince-dbus-p' which should never
error and test if DBUS is available on the system and supported by
Emacs, and if the relevant Evince DBUS interfaces are available.

In case you can reproduce the issue, you could edebug that function to
see where the error occurs.
