Hi,
today, I've updated my fedora (from 2018-04-17, with updates-testing). After reboot, I wasn't able to log in (session just crashed right after typing my password). The bug is already reported in BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1573683

The reason of crash and actual fix for it is pretty weird:
may 02 13:34:48 fanys-laptop gnome-session[1246]: gnome-session-binary[1246]: WARNING: Application 'org.gnome.SettingsDaemon.XSettings.desktop' killed by signal 5
may 02 13:34:48 fanys-laptop gnome-session-binary[1246]: WARNING: Application 'org.gnome.SettingsDaemon.XSettings.desktop' killed by signal 5
may 02 13:34:48 fanys-laptop gsd-xsettings[1960]: Settings schema 'org.cinnamon.desktop.a11y.applications' is not installed
may 02 13:34:48 fanys-laptop systemd-coredump[1941]: Process 1798 (gsd-xsettings) of user 42 dumped core.
(stack trace [1])


In order to fix this, I had to install cinnamon-desktop. After this, I was able to log in, both into Wayland an Xorg session. I never had cinnamon-desktop (or any other cinnamon package) installed on my PC. This fix worked at least on one another computer. I am currently unable to reproduce the issue.
