cups-browsed uses a CPU thread at 100%

[Andy Pearson]

On my Kubuntu Lunar system, with package cups-browsed (2.0~rc1-0ubuntu1.1), cups-browsed is getting stuck inconsistently and some hours after initial boot in a 100% CPU usage loop (seems to use a single thread at 100%).

Looks like https://bugs.launchpad.net/ubuntu/+source/cups-browsed/+bug/2018504 but I am already using the package that appears to contain a fix for that bug, so this may be a different root cause.
