With Fedora 27 mate.
I am able to crash my login session by doing simple scrolling operations in emacs. The .xsession-errors make little sense.
vmware-user: could not open /proc/fs/vmblock/dev
SELinux Troubleshooter: Applet requires SELinux be enabled to run
I did not install vmware and SELinux is disabled. Can easily reproduce by editing any file that has multiple pages and scrolling via line or page keys. This behavior started after a number of large dnf updates. Tried building emacs from source with same results. gedit work ok.
