Description:
even before xbmc in community i had a htpc with xbmc on arch. it is a htpc just for xbmc on my television so my first and only local user is and was 'xbmc'. before xbmc :: 13.0-4 it was only trying to delete my user when i uninstalled xbmc(to get xbmc-git or whatever). that was luckily impossible cause you cant delete a user if it has a running process. but since xbmc :: 13.0-4 you made a password change right after you checked if the user exists. so because of that i had to use a live cd to reset the passwords

Additional info:
getent passwd xbmc > /dev/null || useradd -c 'XBMC user' -u 420 -g xbmc -G audio,video,network,optical -d /var/lib/xbmc -s /sbin/nologin xbmc
passwd -l xbmc > /dev/null <-- makes no sense
