libvirtd crashes on startup

Description of problem: libvirt fails to create a vm which was destroyed by xl command.

Version-Release number of selected component (if applicable): 1.1.2


How reproducible:
Create a vm using libvirt (python), destroy it using xl and create it using libvirt again. It will shows you an error that saying domain is already running. Cannot be destroyed either, restarting libvirtd or redefining a vm with a XML file that has same vm name are the only way to recreate it normally.

Steps to Reproduce:
1. Create a vm using libvirt
2. Destroy a vm using xl 
3. Create a vm using libvirt again 

Actual results:
Fails to create a vm.

Expected results:
Creates a vm normally.

Additional info:

I'm not sure this is relevant, libvirtd crashes with attached log when restarting it after fails to create a vm.

It seems libvirt caught destroy event handler(?) but it failed to cleanup things? 

No error message on libxl.log and libvirt.log.
