I3 and gnome-session

Question

trying to use i3 with gdm and gnome-session, following the same steps as using xmonad and awesome. gnome-session crashes about 30 seconds after it starts. i3 is running properly before that.
/usr/share/xsessions/i3-gnome.desktop:
[Desktop Entry]
Name=i3 GNOME
Comment=Dynamic window manager
TryExec=/usr/bin/gnome-session
Exec=gnome-session --session=i3
Type=XSession
/usr/share/gnome-session/sessions/i3.session
[GNOME Session]
Name=i3 session
RequiredComponents=gnome-settings-daemon;
RequiredProviders=windowmanager;notifications;
DefaultProvider-windowmanager=i3
DefaultProvider-notifications=notification-daemon
~/.xsession-errors (after the i3 init stuff):
gnome-session[9169]: WARNING: Application 'i3.desktop' failed to register before timeout
[src/xcb.c:698] ERROR: X11 connection was closed unexpectedly - maybe your X server terminated / crashed?
(notification-daemon:9225): Gdk-WARNING **: notification-daemon: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"

XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
after 32 requests (32 known processed) with 0 events remaining.
i feel like gnome-session shouldn't crash if it's only throwing a warning. there's not much info here. as far as i know, i3 logs to ~/.xsession-errors anyway.
