I have a fresh install for Ubuntu 16.04, updated, and same issue. After read the peterK (peter-kanderholm) post wrote on 2016-01-08, I couldn't accept it, I do use regular basis a scanner...
Then per the bug reported I did remember the "Color" and "Color Profile Viewer", entered there and almost immediately was recommended to install Gnome Color Manager, accepted. Then twice reboot no bug, no more crashes. I do remember this come after I did plug a second monitor to my laptop, could this be a coincidence?
