This document used to work with dvipng. It is exported from LyX, so I suppose a new version of LyX could have changed something... Whatever it is, seems to happen many times per page.
If nothing else, this needs a better error message. It shouldn't complain about Ghostscript if it's just something dvipng doesn't support. (And, of course, it needs to reap its zombies. Or not spawn them in the first place.) It seems that turning on hyperref support in LyX causes this. I am attaching a fairly minimal testcase.
