So far so good on all the viewers I can find for Fedora 8:

acroread 4.05, 5.0.10, and 8.1.2; aparition;evince; xpdf; kpdf;
gsview.  The older Adobe readers complain:

"This file may contain newer information than this viewer can
support. It may not open or display correctly. Adobe recommends that
you upgrade to the latest version of our Acrobat products. Please

All the viewers except Adobe 8 go to the page with the
figure.   On my (smallish) screen at home, the figure
was displayed at the extreme right edge, so only the
frame was visible.

Don't forget:

5.  some pages are rendered incorrectly (e.g., blank page)

I've been getting this somewhat randomly for fairly
basic documents created using pdftex-1.40.3
but it is not reproducible (except when I'm up against
some deadline!).  Evince sometimes gives a
message that the rasterizer has failed.  Fedora 8
evince uses poppler-0.6.2.  The same documents
can be displayed on my debian system with a newer
poppler, so I suspect something in pdftex-1.40.3
or the fonts (probably in some figure -- the document
uses lmodern) is confusing poppler and acroread.
