Bug description:
SRU justification:
[Impact]
* With automatic login enabled in /etc/gdm/custom.conf, gdm crashes
instead of logging in, and doesn't respawn, dropping to a text console
instead.
[Test Case]
* install gdm and choose it as the default display manager at the
debconf prompt
* create /etc/gdm/custom.conf with contents:
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=some-username
(where "some-username" is a user on the system)
* Reboot (or stop the previous display manager and start gdm)
* In gdm in precise-updates, instead of logging in, gdm crashes, the
system drops to a text console, and a gdm-simple-slave segfault is
recorded in dmesg.
[Regression Potential]
* Minimal. The change consists only of adding a missing NULL parameter
check.
