Given that this is a testsuite failure, I'm assuming that the testsuite will be able to verify the fix and no manual QA work is needed for verification.

Attached patch Better reporting — — Splinter Review 
The root problem here appears to be attempting to use a dead CPOW somewhere but I can't tell where because the error logged is pretty useless and it's too rare to reproduce locally. Right now it just logs the dead CPOW access and points blame into multiProcessShims.js. This patch catches failures to get an object tag and reports an error pointing to the code trying to access the cpow. I'm hoping that by landing this and waiting for this to reproduce again I can at least get some insight into where the faulty code is.

This test was using the shims to get at the session history. I'm still not sure why that is failing but we can avoid the shims entirely by using a frame script to grab the session history we need.
