Heyho!
I had a stubborn segfault at startup behaviour; while investigating I found
a stale /usr/lib/iceweasel/components/libimgicon.so that didn't belong to
any package (I can't remember installing it, left over of a buggy package?)
Removing this library made iceweasel behave again.
But while investigating: I tried to get a backtrack; is the iceweasel-dbg
dependency chain broken when I clear out all recommends (I don't use gnome,
so I can get by with python-xpcom instead of xulrunner gnome support and its
quite big dependency chain:
~$ dpkg -l iceweasel-dbg xulrunner-1.9.1-dbg python-xpcom
...
ii iceweasel-dbg 3.5.6-2 debugging symbols for iceweasel
ii xulrunner-1.9. 1.9.1.6-1 Development files for the Gecko engine libra
ii python-xpcom 1.9.1.6-1 XPCOM bindings for Python
~$ MOZILLA_DISABLE_PLUGINS=1 iceweasel -g
