[Bug-gnuzilla] unable to view google groups (https://groups.google.com)

[grepper]

Hi,

When I go to a selected group in icecat, the page is blank.
For example:
https://groups.google.com/forum/#!forum/tiddlywiki

I am using icecat 17.0.1 downloaded from a gnu/gnuzilla mirror. I have 
also tried in safe mode (all addons/extensions disabled).
The error console shows the following (many duplicate lines removed), 
ending on the "uncaught exception" Error:
