Thank you for taking the time to report this bug and helping to make
Ubuntu better. There have been many changes in Ubuntu since that time

the updates. It would help us a lot if you could test it on a currently
supported Ubuntu version. When you test it and it is still an issue,
kindly upload the updated logs by running apport-collect 216358 and any
other logs that are relevant for this particular issue.
