So for the people that were affected by this crash before and willing to help, can you please install this ppa https://launchpad.net/~azzar1/+archive/ubuntu/gnome-shell-check-nan-2 and wait for the crash to happen and then send me the crash file in /var/crash? There was a problem with apport until few days ago, that's why crash file were not being collected.
