Can you send the output of these:
NewsClipper -e 'test,limit number=10,dumpdata'
NewsClipper -e 'test,limit number=10,grep words="gif" invert,dumpdata'
NewsClipper -e 'test,limit number=10,grep words="gif" invert, \
  grep words="jpg" invert,dumpdata'

Also, if your test handler should never return an image, then I recommend
stripping out images from inside the test handler, using something like:

  @$data = grep { $$_ !~ /(gif|jpg)/i } @$data;

Lastly, you should do your limit after the greps, since the greps may remove
everything from the 10 remaining items...

Thanks,
David
