[Pkg-libvirt-maintainers] Bug#991278: In debian bullseye: libvirtd crashes on virStateShutdownPrepare

Package: libvirt0
Architecture: amd64
Version: 7.0.0-3
Cockpit Machines (cockpit-project.org/) tests caught the following
libvirt crash. The test is pretty basic, essentially starts libvirtd
and calls List APIs for domains, storage, networks, interfaces and
other resources.
SInce this crash heavily depends on the timing of the tests, I was not
able to reproduce with a CLI reproducer.
However take a look in the following stack trace, I got it with debug
symbols installed.
