I also have this problem. It always happens. It might be related to the bug about usernames > 8 chars.
Here's a trace of the syslog when I try to do this: Sep 22 20:32:37 sprite acpid: client 1061[0:0] has disconnected Sep 22 20:32:37 sprite acpid: client connected from 2302[0:0] Sep 22 20:32:37 sprite acpid: 1 client rule loaded Sep 22 20:32:41 sprite gdm-simple-greeter[2339]: GLib-GObject-WARNING: invalid (NULL) pointer instance Sep 22 20:32:41 sprite gdm-simple-greeter[2339]: GLib-GObject-CRITICAL: g_signal_connect_data: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed Sep 22 20:32:41 sprite rtkit-daemon[1825]: Sucessfully made thread 2346 of process 2346 (n/a) owned by '105' high priority at nice level -11.
