This is a problem of older versions of the program ImageMagick that is used by LyX in the background for image conversions. When you update to never versions this should go away.
I also offer ready to print PDFs of some of the manuals here: http://wiki.lyx.org/LyX/DocumentationDevelopment#EmbeddedObjects (I can upload more on demand.) regards Uwe
