Subject Re: FoP 0.94 bug
Date Thu, 10 Jan 2008 16:57:10 GMT

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
