Hello, I also faced that issue and that is a very annoying problem because we are a company and we use LDAP authentication and home directories are mounted via NFS. Most of the machines still runs on 10.04 and only a few have 12.04. The problem occurs only with 12.04. It happens with lightdm and gdm as well so I do not really understand how a fix in the lightdm - 1.2.0-0ubuntu1 package can also solve the gdm problem.
We have the same two syslog lines (as Ballock in original message) : accounts-daemon[ ] segfault error 4 in libdbus-1.so.3.5.8 followed by gdm-session-wor[ ] segfault erroror 4 in libc-2.15.so Sometimes, user can login and syslog only show the first segfault (accounts-daemon). Sometimes users cannot login at all. It "seems" aleatory.

I found it initially in an LDAP-based setup, but to nail down the problem I did a fresh re-install, added: session optional pam_mkhomedir.so umask=0077 skel=/etc/skel to /etc/pam.d/common-session and I removed the home directory of the user used during installation, so the bug has nothing to do with network auth. Anyway - when I login to lightdm I am successfully authenticated and the logon screen disappears, but I am presented with a black screen and nothing happens. I can login from text mode, the homedir is created and afterwards I can login, even using the graphical interface. I tried to see if this is related to lightdm or unity, but if I select Gnome classic, I get the same problem, if I switch to GDM, the problem remains. I am attaching the logs from lightdm. The syslog says: Mar 16 10:31:45 tubuntu kernel: [99829.342230] accounts-daemon[2152]: segfault at 10 ip b76c86c3 sp bfab7640 error 4 in libdbus-1.so.3.5.8[b76a3000+47000] Mar 16 10:31:45 tubuntu kernel: [99829.342545] gdm-session-wor[29440]: segfault at 6e756279 ip b743cd4c sp bf84b250 error 4 in libc-2.15.so[b73ca000+19e000] but I cannot say if this caused the issue or was caused by the issue. I hope somebody can have a look at this. I can help to do some investigating, unfortunately I don't know where to look.
