  Yes, that could cause that kind of problem. Basically the deallocation
within libvirt was dependant on Python garbage collector deallocation of the
unreferenced Python object for the domain, and sometimes this wasn't done
before a new domain with the same name was created again, leading to clash
between libvirt internal cache for the old but still present domain object
and the new one being created.

  I think this bug has been around nearly forever, taking different shape
from an user perspective depending on the situation, and 246198 looks very
much like one of those.
