Bug#742400: iceweasel: This bug reappears in 38.2.1

[Dan DeVoto]

Package: iceweasel
Version: 38.2.1esr-1
Followup-For: Bug #742400

Dear Maintainer,

This bug didn't exist for me in 31.8.0, but now I see it in 38.2.1.  I'm not 
sure about the versions in between.  I created a fresh profile and it didn't 
fix it.  Clicking Customize opens a blank page, and entering 
about:customizing in the address bar also opens a blank page.

Regards,

Dan
