Hello, 
I have a task that seems stuck in webadmin gui, in the sens tha I have "Tasks(1)" listed
The task is  
Restoring VM Snapshot Active VM before the preview of VM snaptest
and the VM is powered down.
Screenshot of expanded steps of task, that actually seem all completed, is here:

Any hint on what to do to clean things? I'm on oVirt 4.1.6.2-1.el7.centos and I would like to clean before upgrading to 4.1.7.

Thanks
Gianluca
