Bug Description
When the first DNS lookup fails with a format error (see attachment captured by Wireshark): No DNS-lookup works, even if I change to a working connection. I can't connect at all to the Internet. I need to restart the computer to get the DNS-system working again with another connection.
If I first connect to the working connection and then switches to the connection that sometimes gives format errors, the errors are ignored and the connection works.
$ lsb_release -rd
Description: Ubuntu 18.04.2 LTS
Release: 18.04
