Comment 41 for bug 1598300

launchpad-groovix: Weird. This "feature" shouldn't be active at all when printer sharing is enabled. Did you look the cups log to make sure that it really is the same problem?

And yes, this is a serious issue, but if you read the earlier messages, you see that the fix will cause the bug 1642966 that will result the breakage of some systems. This really should have been fixed before the release of 16.04 xenial (or the patch that caused this maybe shouldn't have been written in first place since it AFAIK solved a thing that was not really a problem), but it's now too late to do anything to the fact that it was not and it's now difficult to fix it since breakage of systems that have a LTS release installed should be avoided.
