Crash Data

This bug was filed from the Socorro interface and is 
report bp-2835e9ce-d82a-4e98-89be-e74442160428.
=============================================================

There are a small number of crashes reported (single digit number per release cycle, mixed between channels from nightly to esr) in nsAboutCacheEntry::OnStartRequest.  They're all null-dereference crashes, with null mOutputStream (although I only double-checked the minidump of one to verify that it was mOutputStream that's null -- but I also don't see other things that could be on that line).  A query is:
https://crash-stats.mozilla.com/signature/?product=Firefox&date=%3E%3D2015-09-01&signature=nsAboutCacheEntry%3A%3AOnStartRequest&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&page=2

I figured even though they're rare, it's worth filing, since it may be obvious how to handle null here or how to avoid getting here with a null pointer.

From Honza's comment in bug 1266196, he is going to fix this issue there as well.
So I will make this dup of that bug.
