GDM hides users without a valid shell. Could you please attach this file?

Same here (maverick i386). My shell is /bin/bash, which is listed in /etc/shells.

Thank you for your bug report. Did that start in the recent update? Does it happen every time? Does it happen a start or after a logout? It could be a race, I've seen that happening on some boxes after logout

I can not log in at all. I need to install and use xdm to log in, so logging in and out in gdm is not an option. It just started happening this weekend.

For me, those symptoms started with gdm 2.30.4-0ubuntu1.

I second the race condition, since the problem doesn't always appear. Sometimes after booting (minority of cases), the user list is shown normally.

P.S.: Workaround: No need to install xdm. Just log into a VT and enter "startx".

Addition to my previous comment, referring to #4:
- version see above
- doesn't happen everytime, but when it happens (normally directly after booting), restarting gdm (sudo restart gdm) doesn't help.

I found this in the logs after enabling debug messages:
gdm-simple-slave[2092]: DEBUG(+): GdmSlave: Requesting timed login details
gdm-simple-slave[2092]: DEBUG(+): GdmSlave: Got timed login details: 0 0
gdm-simple-slave[2092]: DEBUG(+): Invalid NULL username for auto/timed login

After adding the following to /etc/gdm/custom.conf it works again (don't ask me why):

[daemon]
TimedLoginEnable=false
AutomaticLoginEnable=false

[debug]
Enable=true

Sorry, what I said in #9 is not true. It looks like it just worked once. :-(
