I have the same crash in 18.10: if the screen automatically blanks after
1 minute, gnome crashes and the login screen appears.

Title:
Screen blanking and/or screen lock crashes gnome-shell user session on
wayland - Ubuntu 17.10 beta
Status in mutter package in Ubuntu:
Confirmed
Bug description:
Filed against Xorg due to selection limitations of apport. Mutter is
the best guess of responsible application/package.
Automatic (timed) screen blanking (or manually locking the desktop)
causes the wayland gnome-shell session to crash and drop to user login
prompt. The monitor fades the background to black (but oddly the mouse
cursor does not fade). The monitor blanks and goes into signal search
and then power saving mode. Almost immediately the monitor switches
back on, displaying the login prompt (note login and not unlock as
would be expected). Thereafter the screen stays on indefinitely
without further attempts to blank or power-save.
Ubuntu artful 17.10 beta. Dell monitor at 1920x1080x60hz using hdmi
connected to nvidia card with nouveau drivers on wayland session. Xorg
session seems to work as expected.
/var/crash is empty and manually running Apport and reproducing crash
does not produce a crash report, as Apport crashes with the user
session. Have included Apport output, though I had to select xorg from
limited options in app and this is clearly technically incorrect (xorg
session works fine).
Have attached an exported log file of screen blanking causing the
crash. Blanking probably starts at about the 16:04:22 entry, and the
actual crash seems to happen at 16:04:35.

16:04:22 gnome-shell: Some code accessed the property 'Client' on the module
'dbusMenu'. That property was defined with 'let' or 'const' inside the module.
This was previously supported, but is not correct according to the ES6
standard. Any symbols to be exported from a module must be defined with 'var'.
The property access will work as previously for the time being, but please fix
your code anyway.
...
Crash of gnome-shell can be avoided by changing "Settings - Power -
Power Savings - Blank screen" to "never", and never attempting to lock
the desktop. Alternatively logging in to a Xorg session seems to avoid
crashes.
