"No such child: driver" error.

[Quicksy]

I have Wok and Kimchi installed on Ubuntu 18.04. It used to work fine on last week, but today when I'm trying to clone my VM or even navigate to the "Virtualization -> Guests" tab, I get red message "No such child: driver": I can see the following messages in wok-error.log:

Could you help me to understand what happened and how can I fix this?

I've just finished up the tests of the next release on Ubuntu 19.10 and it is working fine. Could you give it a try?
