This crash seems to be the result of an owner change of a DBus object (or interface?) owned by the Music lens.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

As part of the big bug clear up for 16.04 LTS I am marking this bug as Wont Fix. These types of crasher are better handled by errors.ubutnu.com which can collate similar crash reports to help us identify persitent bugs rather than one-off crashes. Sorry we are not able to help with this specific issue. If you are still experiencing this crash, please re-open the bug and add the tag “desktop-bugscrub-reopen”. See https://wiki.ubuntu.com/BigDesktopBugScrub for more information.
