Comment 2 for bug 1100308

This issue is reproducible and seems to be related to the user number. I had a user number in the /etc/passwd set to 300 and something. Now changing that to 1000 and with appropriate "sudo chown -R myusername /home/myusername" and "sudo chgrp -R myusername /home/myusername" I no longer get the error: the username is shown in lightdm, the username is shown in the upper right corner, I see my self in the "User account" is system settings, and pressing the icon does not generate a crash, but selects the icon alright.

Before that I tried "minimum-uid=300" in /etc/lightdm/users.conf" but I did not get that to work.

There seems to be multiple issues (including a crash) related to a too low user number.
