Hi!

When I quit my Xserver, I sometimes (not always) get the
following message on my console, but not in any log files
AFAICT: 

waiting for X server to shut down utmp_update: Current user `wiz' does not match
 `' in utmpx entry

That's on 3.99.5/i386. I usually start the X server with
"startx" and open two rxvt windows.

Additionally, just now, when logging out, I got:
May 27 10:28:54 hiro login: pam_sm_close_session(): no utmp record for console
on the console and into /var/log/authlog.

Has anyone else seen these?

Any ideas what could cause them?
 Thomas
