[Jakub Libosvar]

The test failure doesn't report much:

Hi:

Because I didn't check the previous opened bugs, I created a new one being a duplicate of this one: https://bugs.launchpad.net/neutron/+bug/1912369.

I suggest not to close 1912369 as a duplicate because I already pushed some changes pointing to it.

Regards.
