Is it still the case for Ubuntu 11.10 final?
(In reply to comment #4) > Is it still the case for Ubuntu 11.10 final? According to the Launchpad reporter, no. The bug was closed as "invalid" on launchpad. OTOH, this really seems to be a duplicate of #40526 (both are forwards from launchpad, they were also suggested as duplicates on Launchpad, but one of the Launchpad bugs was marked as Invalid and the other is still open). - Close? (since the original Launchpad bug was closed) - Dupe of #40526?
