journal log right after crash

I can reproduce this every time I attempt to unlock the screen while using the GNOME Wayland session.

I'm attaching my journal log for the time period when it happened. Noteworthy is:

Jan 26 09:55:04 sgallagh540.sgallagh.rht /usr/libexec/gdm-x-session[17675]: Unable to run X server

(Which of course should not be happening on the Wayland session)

This started happening only with GNOME 3.19.4.

Working in the latest Rawhide build.
