[Zope] Errors Viewing PDF Files

[Edward Pollard]

Our site has some PDF's in the ZODB.

The files don't show up properly inside the Acrobat plugin. Pages are 
missing.

Browsers that save the entire file locally to disk are unaffected.

Traceback (innermost last):
   Module ZPublisher.Publish, line 98, in publish
   Module ZPublisher.mapply, line 88, in mapply
   Module ZPublisher.Publish, line 39, in call_object
   Module OFS.Image, line 328, in index_html
KeyError: 65536

The KeyError value varies from viewing to viewing.

Although it says OFS.Image, I checked and these ARE file objects.

Thoughts?
