Comment 6 for bug 1153587

Thanks, Chris!
Could you also guide me to some instructions how to install these commits?
Sorry, but I haven't dared tinkering with my system at that level yet, but
having no alternatives, I may have to do it. My system is barely usable
right now.
Thanks for your patience!
