It is _definitely_ a bug in the Omega fonts.  I recommend that you do
the following: use
M-x set-variable RET preview-fast-conversion RET nil RET
This will make all graphics be created in their own, single EPS file.
Then run C-c C-p C-d as this will make only those graphics fail that
contain the font(s) in question.  It will be the conveniently the case
that all other EPS files will get deleted from the temporary
directory.  Try tracking down the fonts in question as good as
possible, then send a bug report to the author of the fonts.

The next release of preview-latex will ignore such errors.  This is
actually not a good thing to do, but AUCTeX central is not the right
institution to do the debugging and take the blame for other people's
bad PostScript code.

You will be glad to hear that your example works perfectly at my site
now (I actually had to do another fix for the parsing of error
