Description

[Ben Kelly [:bkelly, not reviewing]]

This bug was filed from the Socorro interface and is 
report bp-4501f57e-4fc1-4f36-bdd2-e9fe32161219.
=============================================================

We are hitting some strange large OOM crashes from image loading.  The ImageCacheKey is trying to find out if it has a controlled document or not by using SWM.  The stack claims we are blowing up inside the SWM hash lookup.

The weird thing is, though, it also claims we are using strings, but we are not.

About 700 crashes in the last month.

I think we should see what happens when bug 1320196 merges to release channel in a couple weeks.  Its possible this is the same crash but the stacks are confused.

Bug 1297300 might have affected this too, it also landed on the 51 train.

Haven't seen the crash report for a long while. Free free to reopen it if the issue is still valid.
