Description

Hi folks,

as some of you might know, I am currently testing the JHOVE GIF module, for now running it against a test corupus of 48,000 files and also running the same test suite against ImageMagick, Metadata Extractor and Bad Peggy.

There is this one file, that JHOVE misses, although it:

• cannot be rendered by the IE
• is flagged as invalid by ImageMagick, the Metadata Extractor and Bad Peggy

As it has a valid header and a valid trailer, maybe there is something that JHOVE does not check yet.
I myself will further investigate, too, but just in case someone is working at the GIF module currently, this file might help.

Best, Yvonne
