Task:

            "task_name": "do_unpack",
            "message": "recipe dbus-1.6.10-r6.0: task do_unpack: Succeeded",

        }

But the task is executed (as you can see in the task log file attached) and the outcome of the task is 0 (SUCCESS). 

In case an task is not executed the outcome should have the value COVERED,  SSTATE or EXISTING.

This problem appeared when building:

        "model": "orm.build",
        "fields": {
