On my Debian 4.0 (etch) (stable) platform the problem is fixed by
commenting out lines 73 and 74 of the file fontEncoding.properties
in the directory /usr/lib/iceweasel/res/fonts.  (This then makes
the iceweasel's "res" tree match that of mozilla.com's firefox
apart from two extra directories provided with iceweasel.)

Thus,
73,74c73,74
< encoding.symbol.ttf = Adobe-Symbol-Encoding
< encoding.symbol.ftcmap = mac_roman
---
> #encoding.symbol.ttf = Adobe-Symbol-Encoding
> #encoding.symbol.ftcmap = mac_roman

In fact, the copy I had was datestamped Oct 25 01:57 (EDT), i.e., it
was rather fresh when I first raised the issue.

But I don't know if commenting out these lines is the definitive way
to deal with the issue in Debian-stable.

I think it's important for such distributions to work out of the box
as much as possible ( for the moment that means assuming the user has
followed the directions at
http://www.mozilla.org/projects/mathml/fonts/ ).

With this change there seems to no longer be a problem if
pango is enabled although at this moment to my taste the fonts
look somewhat better when pango is disabled.

How should this be reported to Debian?

Many thanks.
