jpegs with errors not possible to scan

Description

It seems FuzzyOCR is not able to scan JPEGs that have decoding errors. The attached JPEG is 80% displayed by viewers (incl Thunderbird), but jpegtopnm exits with error code 512, and FuzzyOCR has to skip all tests: 

2007-01-04 16:16:13 [11062] Exec  : /usr/local/bin/jpegtopnm /tmp/.spamassassin11056HIEob3tmp/dogat66.jpg
2007-01-04 16:16:13 [11056] /usr/local/bin/jpegtopnm: Returned [512], skipping...

This is a known issue, and it isn't directly FuzzyOcr?'s problem. The Netpbm part for jpegs (jpegtopnm), does not handle errors at all, and I don't know of any programs that can fix such broken jpegs...

If you know any, tell me :)
