Re: FoP 0.94 bug
Nancy,
I'm merging the new image package into FOP Trunk later today. That
should improve the situation. However, I would still appreciate if you
could send me the PNG that didn't work so I can make sure it will work
with the new package. Thanks.

Re: FoP 0.94 bug

Hi dear Jeremias,
Unfortunately, I have committed a new png with this icon, which is a bit
larger than the previous one (may be a couple of pixels) and FOP 0.94 "ate"
it without vomiting. The problem was really weird.
My best wishes,
Nancy
