Yes, that means that an attempt to execute "/usr/bin/jpegtopnm" failed
OR it ran and terminated with a non-zero exit code. So for example, if
a spam contains a corrupt image jpegtopnm will exit with a failure status
when it attempts to do the conversion and throw that kind of error.
I saw the exact same errors in my FuzzyOcr logs, so created a shell-script
wrapper for jpegtopnm which captured its 'stderr' and found:
jpegtopnm.exe: End-of-file encountered in the middle of JPEG image.
that correltated to those errors. So borked spam-rat-ware.
Hmm, spammers rat-ware having bugs in it, who'd a thought it. ;)
