Hello and thanks for you follow up! Happy to hear that you found the root cause of the issue. As this was a local configuration problem rather than a bug in Ubuntu I'm setting the status of this bug to Invalid. Should you believe there is actually a bug here please comment back with your findings and change the bug status back to New, we'll look at it again. Thanks!
