This is actually very likely. It is a problem that is not so easy to fix: ssh
uses unix sockets, therefore the connection is considered local and thus the
shared memory extension is used. Everything seems to work well - until you try
to access the shared memory areas (which are on the other machine).

In fact, I had plans once to address this in the libxcb backend of Qt5 but
never got around to it.

The crash happens in Qt5 - I would therefore start looking there ...

So, in fact, why do you assign this ticket to 'X.Org'? Because you surmise that
you will get some response while assigning it to 'Other' nobody cares?
