Bug#608009: looks like a libgtk issue

[Mahesh T. Pai]

I remembered that I had upgraded libgtk related libraries the day
before the issue started. 

So, looked into the apt archives, and reverted to the following
packages, and the problem has vanished.

libgtk2.0-0_2.23.2-1_amd64.deb 
libgtk2.0-bin_2.23.2-1_all.deb 
libgtk2.0-common_2.23.2-1_all.deb 

Downgrading iceweasel itself has not helped; so it is a problem with
the libraries.
