Details

These shutdown hang reports are being reported as [@ IPCError-browser | ShutDownKill] now.

I still see at least one instance of a shutdownhang ( bp-2c4ceef6-6ee3-4995-bb35-54aea0171220 ) but mostly they are not. Trevor Skywalker seems to have noticed this first on 12-8 in bug 1424451.
It is possible that I'm completely confused about this and shutdownhang was not the top crash.
Hmm never mind. I went back and looked at older reports, and I guess this was always the signature. Sorry for the confusion.

I don't think the processor for shutdownhang signature is broken. There are still many signatures containing "shutdownhang". 

https://crash-stats.mozilla.com/search/?signature=shutdownhang&product=Firefox&date=%3E%3D2017-12-15T23%3A12%3A47.000Z&date=%3C2017-12-22T23%3A12%3A47.000Z&_sort=-date&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature	

Shows 50 signatures containing the term "shutdownhang" accounting for 186,115 Crash Reports over the past 7 days.

Shutdownhang crashes are still top crashers though. 

Do they have a [meta] bug to help with organization? 
(Should they have a [meta] bug?)
