What happens if you try to run

iceweasel --safe-mode

or

MOZ_DISABLE_PANGO=1 iceweasel --safe-mode

or

LANG=C iceweasel --safe-mode

?

/usr/lib/iceweasel/firefox-bin links against pango libraries which are
part of libpango1.0-0. If you decide to file a bug then it probably
should be filed against that package.

What output do you get if you run (as root)

/usr/bin/defoma-app -v update pango

Try to downgrade libpango1.0-0 and libpango1.0-common.

If you did not deliberately override apt's package verification
mechanism then you should be safe.
