First found this bug when I copied some files into /opt/ via root access
nautilus. After clicking on another window, Ubuntu froze.

This happened again and possibly recreated by performing root operations
and navigating around gnome.

Here is something I found interesting in the /var/log/syslog:

Oct 22 19:03:14 hiruna-ubuntu-XPS kernel: [ 9031.695578] traps: gnome-
shell[1813] general protection ip:7f91e14a6de2 sp:7ffd8ed31070 error:0
in libgobject-2.0.so.0.5400.1[7f91e1471000+52000]

This ^ was about the time when it froze the laptop.

Also it should be noted that this keeps repeating over and over:
