All I can think of at this point is permissions issues somehow.

The FuzzyOcr/Misc.pm might be masking the real exit code.  It evals a bunch
of Perl code in the child process and then:

         # couldn't open file descriptors or exec failed
         chomp($@); my($msg) = "save_execute: $@\n";
         # try to get some attention, log and stderr may be closed
         POSIX::write(2,$msg,length($msg));  print STDERR $msg;
         POSIX::_exit(8);  # must avoid END and destructor processing!

So anything in that eval before the exec() could be dying, or the exec
could be failing... we have no idea.

(That's some of the worst Perl code I've read in a while, btw...)

Some googling on "fuzzyocr 2048" was leading me to suspect that as well.

I just now went back to the OP's very first message containing the full log, and noticed this:

save_execute: Insecure dependency in open while running with -T switch at 
/etc/mail/spamassassin/FuzzyOcr/Misc.pm line 92.
save_execute: Insecure dependency in open while running with -T switch at 
/etc/mail/spamassassin/FuzzyOcr/Misc.pm line 92.

This is relevant and may be the cause. I was gooling "fuzzyocr 2048" and saw mention of this, but didn't realize that it was relevant here.

polloxx, hit this URL; I remember seeing various patches for FuzzyOCR to address this.

You said you're using debain squeeze...

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=571218

The debian maintainers claim it's fixed in 3.6.0-2. Did FuzzyOCR get updated when you ran your apt-get?

And my apologies for not getting to this point earlier.
