mutter 47.3 crashes as soon as user types character into window in RDP gnome-remote-desktop screen sharing session

1. Log into a GNOME session.
2. Configure the session for RDP screen-sharing via gnome-remote-desktop.
3. Install and enable the Allow Locked Remote Desktop gnome-shell extension.
4. Lock the screen.
5. Attempt to remote into the desktop from another computer.
6. As soon as you type a single character through RDP into the password field to unlock the screen. the following happens:
   1. Your remote desktop client disconnects.
   2. The gnome-shell "Oops!" screen flashes briefly.
   3. The lock screen comes back and the password field is filled in with a bunch of characters even though you only typed one.
7. Clear the password and type your password to unlock the screen.
8. Observe that there is now an "Oops!" screen and you need to kill your session and log back in.

This worked fine with gnome-remote-desktop 47.0.

The only thing Allow Locked Remote Access does is replace the inhibit_remote_access function in the Remote Access Controller with a function that does nothing. The intended behavior of this function has not, as far as I can tell, changed recently, so I don't think the problem here is in Allow Locked Remote Desktop.
