Xwayland crashed with SIGABRT in OsAbort()

[Edson T. Marques]

I updated ubuntu just now and came the new version (3.27.91) of gnome-shell and gnome-shell-common.
After the update I restarted the computer and it was not possible to stabilize the system in the login interface. That is, it seems that at the end of the initial load of the system, as soon as plymouth finishes and should enter gdm, the system ran into a loop, restarting afterwards, without being able to load the gdm interface.
I had to revert to the previous version of gnome-shell and gnome-shell-common to get back to working.
