if you look here: http://www.widsets.com/forum/posts/list/287.page
(googled for "LUT has improper length")

you'll find it says: 'This error is due to an
internal bug on currently used JDKs ImageIO class'

what version of java do you have? May be worth updating. Or if you
can't update, then you'll have to change the format of the png.

Could the reason of the error be the transparent background? Or is it a
problem of FOP?
