My own 2 cents is that I'd like to see a much longer stack to see some more
details of this particular example, i.e. --num-callers=50 or something. We get
quite a few crash-on-shutdown traces in fedora as our crash-reporting
infrastructure is global over all apps and over their entire lifetime. And they
fall into two main categories. 

I've seen ones like this one with a11y shutdown where the a11y shutdown and
release of uno references is called effectively from "spi_atk_bridge_exit_func"
which nightmarishly is called from atexit from the accessibility libs which
makes avoiding this tricky.

The other family is due to the current cppu shutdown being crippled to attempt
to "leak" resources to avoid accessing dead ones, but this has the side effect
of not calling the dtors which cleanly bring down the remotebridge reader/writer
threads leaving them generally blocked on mutexes and then after those global
mutex gets destroyed on main processes exit the threads unblock and trample all
over the corrupt corpse of OOo. The common case is unopkg crashes which are no
fault of unopkg. See issue 107490 for some thoughts on fixing that up.
