1311862 - Crash in nsWrapperCache::GetWrapper

Status: RESOLVED FIXED

(Core :: IPC, defect)

Description

[Andrew McCreight [:mccr8]]

This bug was filed from the Socorro interface and is 
report bp-f91b1528-a36b-46a0-af27-3dd982161016.
=============================================================

I think this is a variation on bug 1309958. That bug fixed the case of some kind of CPOW stuff happening in PScreenManagerChild::SendScreenForBrowser, but I'm also seeing a few crashes involving PScreenManagerChild::SendScreenRefresh(). I assume the patch there is not expected to fix this, too.

This is pretty similar to the other PScreenManager ones.

Is 51 affected? Should we uplift?
