FuzzyOCR has a couple of grossly exaggerated default scores values,
and some of its decisions are plain wrong (e.g. sloppy parsing of
MIME file name extensions). Here are a couple of its settings,
trimmed to a sane value:

focr_threshold 0.20
focr_base_score 1.9
focr_add_score 0.4
focr_wrongctype_score 0.1
# Does silly things (parses Content-ID) when filename is missing!
focr_wrongext_score 0.1
focr_corrupt_score 1.9
focr_corrupt_unfixable_score 3
focr_autodisable_negative_score -50

and image hashing is worse than none and should be disabled:

focr_enable_image_hashing 0
