Log of failing GDM slave

Description of problem:
gdm blows up when responding to interface=org.gnome.DisplayManager.Session method=SavedLanguageNameRead signal during login. The attached trace appears to 
show a null pointer deference on the 'settings' variable:

gdm[1464]: #6  gdm_session_settings_is_loaded (settings=0x0) at gdm-session-settings.c:246
gdm[1464]: #7  0x00000000004086a8 in on_settings_is_loaded_changed (worker=0x144ac40) at gdm-session-worker.c:2114
gdm[1464]: #8  0x00000036c940e2ee in g_closure_invoke () from /lib64/libgobject-2.0.so.0

Version-Release number of selected component (if applicable): 2.91.93-1

How reproducible: about 70% of the time

Steps to Reproduce:
1. Boot system
2. Try to login
Seem especially reproducible if automatic login is enabled but occasionally happens on manual login, as well.

Usually, attempting to log in a second time results in success.

Actual results:
gdm slave crashes with attached backtrace and login process freezes with spinning wait cursor.

Will this negatively affect the autologin for the GNOME 3 test day ISO's being spun tonight?
