Still trying to debug SA crashing with the OCR plugin.  I extracted the
base64 encoding from one of the offending messages.  Then I converted it
to image001.gif with uudeview.  But when I try to convert it to a pnm
file from the command line I get errors.

[filter]# giftopnm image001.gif > image001.pnm
giftopnm: too much input data, ignoring extra...
giftopnm: bogus character 0x00, ignoring
[filter]#

I have no idea what's causing this, how to fix it, or if it's even
related to the crashing problem.

This OCR stuff looks promising.  Any comments on performance?  How much
extra load does it put on a 
server?
