Bug Description
I started QtCreator and my system hung completely during startup, so I hard rebooted.
When I started QtCreator again I was unable to access the network, and the syslog was full of
dnsmasq[6046]: Maximum number of concurrent DNS queries reached (max: 150)
I deleted the device-i386 LXD container which also seemed to cause this if it was running without starting QtCreator. Running QtCreator after deleting this still causes the flood of queries.
