** Description changed: + 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. + + Original description: + Chrash happend while trying to change a desktop-icon. Searching the icon in a hidden folder ".xxxx" in the user directory.
