Subject: bug#14668: 24.3; htmlfontify-buffer under emacs -nw produces blank page

From: regcl <[email-masked]>
Date: Wed, 19 Jun 2013 15:36:46 -0400

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 ...
