Did my daily smxi routine this morning and iceweasel was one of the packages upgraded in sid.
After that...no Iceweasel.
Tried reinstalling and still no go.
Downgraded to the version in the squeeze repo's and back in business.

I encountered that issue as well, but on my Aptosid desktop (AMD64) did not have a problem with upgrade of Iceweasel

I held Iceweasel back for now too as I can't find any bug report yet for this.

it is fixed with iceweasel 7.0.1-4 , so wait for your mirrors to sync.
here is the bug report:
========= SCRAPER REMOVED AN EMBEDDED LINK HERE ===========

Great...thanks for letting us know

Fixed with new 7.0.1-4 version (already available in Greek mirror)

It works now with the updated package __{{emoticon}}__
