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

In my case the crash seemed to happen after downloading extra packets and the "verification of packets to be deleted" (approximative translation from French).

My logs are attached on the (duplicate I think) bug I reported here : https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/856758

Bug happened again even with formatting previous existing partitions.
Eventually succeeded by unplugging Ethernet so no update would occur during installation !
Hope it can help !
