The daemon crashes due to unexpected cleanup happening due to bad
assumptions about locking and state. See patch 5.
Peter Krempa (12):
qemuBlockJobProcessEventConcludedBackup: Handle potentially NULL
'job->disk'
qemuDomainDiskPrivateDispose: Prevent dangling 'disk' pointer in
blockjob data
qemuDomainDeviceBackendChardevForeach: Fix typo in comment
qemuDomainObjWait: Add documentation
qemuProcessStop: Prevent crash when qemuDomainObjStopWorker() unlocks
the VM
qemuProcessStop: Move code not depending on 'vm->def->id' after reset
of the ID
qemu: process: Ensure that 'beingDestroyed' gets cleared only after VM
id is reset
qemu: domain: Introduce qemuDomainObjIsActive helper
qemu: migration: Properly check for live VM after qemuDomainObjWait()
qemu: migration: Inline 'qemuMigrationDstFinishResume()'
qemuMigrationSrcRun: Re-check whether VM is active before accessing
job data

error paths
