system collapses when user presses 'next' in the wizard with dbus 1.10.6-1ubuntu3.2

The direct cause for the collapse is the lack of session dbus: bug #1654365

Another question is why is the image built with proposed?

There's all kinds of other crashes going on that I'll be filing bugs for.

unity-system-compositor: bug #1654536

click: bug #1654543 (unlikely to be a bigger problem)

diff of the rootfs between 102 (last known good image) and 116
device tarballs are identical

Images have been rebuilt with proposed disabled and boot successfully now. I added a comment to the SRU bug 1644323 and marked it as verification-failed. I'm closing this report.

Reopening until root cause of the problem with dbus 1.10.6-1ubuntu3.2 in xenial-proposed is fixed and unblock the promotion of dbus to xenial updates.

Hello Jean-Baptiste, or anyone else affected,

Accepted dbus into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/dbus/1.10.6-1ubuntu3.3 in a few hours, and then in the -proposed repository.
