To reproduce the bug ...
emacs -Q -nw
C-x C-f foo.html
... paste text between the '***'s below into buffer foo.html ...
***
<!DOCTYPE html>
<html>
<head><title>Foo</title></head>
<body>
<h2>this is Foo</h2>
</body>
</html>
***
C-x C-s
M-x htmlfontify-buffer
C-x C-s foo.html.nw.html
Now open foo.html.nw.html to see a blank page.
Note: The page contains text styled in such a way as to be invisible.
Compare foo.html.nw.html with this
emacs -Q
C-x C-f foo.html
M-x htmlfontify-buffer
C-x C-s
... to see ...

Thanks. I'm surprised this doesn't work. There seem to be two issues:
"unspecified-fg" and "unspecified-bg" colours, and the fact that font
:height == 1 in ttys. This hack seems to fix it:
