cpp file in emacs (external viewer error)

[Samj]

Hi

I have a problem opening a .cpp file with emacs
using debian testing kernal 2.6.15 and emacs21 21.4a-3, I googled, search variables and help docs, asked at different forum for no avail.
the problem happens only when I start emacs as a user but it does not happen when I start it as root. I am enclosing the error below as well as my .emacs and c++ related .emacs-mc394
thanks

ctl-xf which does find/create a file then I type test.cpp then I get
this in the echo area

I deleted every thing in .emacs reloaded the file and the problem is
still there.
it is only when I delete .emacs from my home dir and restart emacs that the problem does
not duplicate.

[Samj]

ok, I fix the problem at least for just now.
I commented out the section

===================================
;; ;; opens a a file 'pdf' with xpdf and so on...
;; (require 'extview)
;; (push '("\\.pdf$" . "xpdf %s") extview-application-associations)
;; (push '("\\.py$" . nil) extview-application-associations)
===================================
restarted emacs and I am now cpp compliant. no clue as to how to fix the problem so that I can have the functionality provided by the section above.
