This bug was filed from the Socorro interface and is report bp-e4666f13-6df5-4e1e-9149-029df2110823 . ============================================================= Got there while trying to open about:memory
It's a null-deref; is it possible for |windows| to come back null? I'd think so, if the IPC message races shutdown.

Yes, but I'm talking about shutdown of the content process, not the chrome process. I wouldn't expect it to be happening in this case yet, so presumably the null is for a different reason, but once we move to process-per-tab content processes will be shutting down all the time.
Created attachment 555353 [details] [diff] [review] Patch v1 Let's try that patch. I see only two reasons why |windows| could be null: whether nsGlobalWindow ctor has never been called or nsGlobalWindow::Shutdown has been called. I have a patch adding a ::Init method to nsGlobalWindow which would remove the requirement of nsGlobalWindow ctor being called. Though, it seems unlikely that the ctor isn't called... but I don't know that much our e10s architecture... Anyway, this patch should not hurt I believe ;)

I don't know how, I didn't see this review has been done... Thanks for the reminder Boris :)
