[tex4ht] Bad interaction with bookmark.sty

To round off this issue, the author of dvipng has agreed to revise it for the next release, presumably 1.18. The problem, if I understand it correctly, is that the bookmark dvips driver, which is used by default, inserts what is essentially an empty image, which dvipng does not expect, and when trying to compute the resolution it divides by zero. The bookmark dvips driver works as it does to avoid a clash with another package; I think that was the recent change that upsets dvipng.

Regardless of the input, it is a bad bug in dvipng. Programs should not crash. If it is possible for someone to send me the dvi file, I could send it to the maintainer. (Or feel free to send it directly :) I won't have a chance myself to extract the dvi file that's being fed to dvipng for a while, at best. --thanks, karl.
