arev.sty conflicts with a couple of packages that are included by default
when latex fragments are converted into images:

o \usepackage[mathscr]{eucal}
o \usepackage{wasysym}

Since the latex compilation of the fragment fails, no .dvi and no .png
files are produced.  If you delete arev from your header, the conflicts
go away and everything works. 

The conflict with eucal elicits the message:

Then the conflict with wasysym elicits the message:

If I comment those two out of the (temporary) fragment latex file,
the compilation goes through without any problems, so these are the
only conflicts.

Now that I've made the diagnosis, I'll let you worry about the
cure ;-)

HTH,
