Unable to parse EXIF that exiftool is able to parse

[GoogleCodeExporter]

Attached file imports into camlistore 0.8 as an image with correct tagging of 
image size but no other EXIF attributes.  

camtool debug exif 2002-06-28_23.59.15.jpg
gives following error:
exif.Decode: exif: sub-IFD decode failed: tiff: tag format read failed: EOF

Perl-based exiftool is able to extract dozens of attributes correctly:

Currently I'm on the actual dev version and we also can't index any metadata, 
but camtool don't gets the same error:

We're in the process of updating our 3rd party EXIF library. Please bear with 
us while this is done and I'll come back to check on that issue right after.

It looks like both these images have broken tiff tags, which is correctly 
resulting in an error from goexif. However, we might try and do something to 
still use whatever non broken info is in these files.

Here's a start of a discussion upstream:
