** This bug has been marked a duplicate of bug 1004515 segfault in accounts-daemon when logging in / gdm crash if user account is added or deleted -- You received this bug notification because you are a member of DX Packages, which is subscribed to accountsservice in Ubuntu. Matching subscriptions: dx-packages https://bugs.launchpad.net/bugs/1255356 Title: gdm-session-worker crashed with SIGSEGV in malloc_consolidate() Status in “accountsservice” package in Ubuntu: New Bug description: On an otherwise clean and up-to-date precise installation, the conditions to reproduce this gdm crash seem to be: * libnss-ldapd is installed and configured for at least passwd lookups in nsswitch. * the LDAP user being tested is not in the gdm user list. After filling in credentials and pressing Login, gdm-session-worker crashes and the login screen hangs waiting for it. For a user who is already shown in the list, whether because of being present in /etc/passwd or the wtmp history, logging in seems to work normally. I don't know whether this bug is in gdm, nss-pam-ldapd, accountsservice, or somewhere else, but gdm seems like a reasonable place to start.
