I had a similar problem, but I was under RH 7.0: graphics would
*never* show up under Lyx 1.2.1.
This weekend I got pissed about it and after a while I came to the
idea of reinstalling ImageMagick, uploading from 5.3.3. to 5.5.*.
It worked... seems that "convert" was failing before.
In any case there is room for improvement in the way images are
handled now, because the text jumps to the beginning when a new
image is rendered, and the conversion process takes a long time
in a document with several of them. Maybe the procedures should be
reviewed somehow..
