I can confirm this segfault on 12.04:

For some users on trying to log in, these lines appear in /var/log/syslog:

Sep 28 11:25:02 smaxx04 automount[1111]: syntax error in nsswitch config near [ syntax error ]

gdm then hangs on the password entry stage, it can only be set back to the login screen by 'service gdm restart'. It should probably be noted that this only happens for some users and some of the time. The home directories are automounted via NFS, authentication is provided over LDAP, afaik.

/var/crash is empty by the way, with enabled=1 in /etc/default/apport
