doc-view stuck on same image

[harold . carr]

With

    GNU Emacs 24.3.1 (x86_64-apple-darwin11.4.2, NS apple-appkit-1138.51)
of 2013-03-31 on tenseven-slave.macports.org

when I use doc-view (automatically) when visiting *.pdf, *.tiff, *.ps,
etc., files it either:

- keeps showing me the same image (no matter what page or file I visit)
  - usual the image show in the *GNU Emacs* buffer
- starts using HIGH CPU doing what?  - I finally just kill it

It used to work fast and fine.  Unfortunately I do not know what I did
differently (i.e., emacs version, config settings) when this started
happening.

Any ideas?
