I have to log in twice after update

[Wade Smart]

I just installed this mornings updates and upon
reboot, I put in my password and everything that
was on my screen when I shut down was back
up on my screen - then the screen blinked and
returned to the login screen, where I then logged
in again and my screen was empty.

I shut down, brought it back up, logged in, came
to a empty desktop then my screen blinked and
returned to the login screen again.

Scanning the log this is what stands out:

Apr 14 08:25:40
gnome-session[9366]:
GLib-CRITICAL: g_environ_setenv: assertion 'value != NULL' failed

Apr 14 08:26:13
gnome-session[9366]:

Apr 14 08:26:14
gnome-session[9366]:
CRITICAL: We failed, but the fail whale is dead. Sorry....

Suggestions on how this may be fixed?
