So commit 306b3a8504 tried mimicking behaviour of commit 540c339a25, but added a virObjectRef(vm) only after virDomainObjListAdd() in lxcDomainDefineXMLFlags() and not in lxcDomainCreateXMLWithFiles(). That way undefining a domain that was started with different XML than defined will leave the domain object in a state with not enough references to then remove it. Hence any lxcDomainDestroyFlags() called afterwards crashes the daemon.
