gdm errors on shutdown

[Rick Dooling <rpdooling@gmail.com>]

When I shutdown or restrart from gdm, I get the following showing up
in my log:

Apr 13 07:54:12 debian gdm[7927]: CRITICAL: gdm_connection_close:
assertion `conn != NULL' failed
Apr 13 07:54:12 debian last message repeated 2 times
Apr 13 07:54:12 debian gdm[3436]: WARNING: gdm_cleanup_children: child
7927 crashed of signal 11
Apr 13 07:54:12 debian gdm[3436]: WARNING: gdm_cleanup_children: Slave
crashed, killing its children

I've searched on selected terms without finding anything.

Anybody have an idea. It seems harmless.

Thanks,

RD
