Seems like you're hitting an old bug[1] where 'blockcopy' (or 'blockcommit') missed to execute a cleanup routine which destroys a reference to the active block operation -- resulting in the error you're seeing when you attempted to 'abort' the block operation manually. This bug is fixed in libvirt-1.2.8 and above. I see you're using libvirt-1.2.7, if you can update libvirt in your environment, that should fix your issue.
