User Accounts reports wrong "Automatic Login" status when upgading from 12.04

[Albert Astals Cid]

[Impact]
A lightdm user in Ubuntu 12.10 and 13.04 will always see automatic login as turned off, even when it is currently enabled for that user. This does not affect the functioning of autologin itself, just whether it appears enabled or not. This may lead to user confusion, and is a regression from 12.04.

[Reproduction steps]
0) Be on Ubuntu 12.10
1) Go to System Settings -> Users
2) Unlock the pane
3) Toggle "Automatic login" on for a given user
4) Reboot
5) Go back to System Settings -> Users
6) Note the value of "Automatic login"

[Regression Potential]
Low. Only affects a code path that decides whether to check the gdm value or the lightdm value for autologin. Previously, a logic bug meant that we always checked the gdm value.

Status changed to 'Confirmed' because the bug affects multiple users.

It's actually an accountsservice bug

Diff over the existing 0007-add-lightdm-support.patch

You can create almost any dbus proxy and it will be non null even if there is nothing there, that's why i added the check that there is an owner

Whole new 0007-add-lightdm-support.patch (result of applying the patch in the previous comment to the existing 0007-add-lightdm-support.patch)

New partial diff, old one is wrong

[Albert Astals Cid (aacid)]

New full diff, the old one was wrong

[Michael Terry (mterry)]

Thanks, Albert! I'll assign to me for an SRU.

[Michael Terry (mterry)]

Got back to looking at this, and I'm confused. Albert, that patch is already in 12.10...

[Michael Terry (mterry)]

(Just want to be sure I'm grabbing the right diff). The latest one you said was the full diff is the same as what's in quantal. Can you upload the correct patch again?

[Albert Astals Cid (aacid)]

Sigh, patches of patches are a pain :-/

[Albert Astals Cid (aacid)]

New patches attached, they should be the correct ones now, sorry for the mess :-/

[Alistair Buxton (a-j-buxton)]

This doesn't just affect upgrade installs. It affects completely fresh installs too. All you have to do is enable automatic login, restart the computer, and open User Accounts, and the setting is wrong.
