Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone.
Comment 2 Allon Mureinik 2016-09-08 09:27:14 UTC 
Tal, does this ring any bells?
Comment 3 Tal Nisan 2016-09-19 11:07:16 UTC 
Couldn't reproduce after numerous reproduction attempts in any constellation I can think of.
In any case the NPE is only in the UI thread that attempts to gather the VM<->Disk data and does not affect any backend flow.
Closing for now as works for me until new information or clearer steps to reproduce will be prodived
