=== User Account ===
For stupid reasons, it's necessary that Sugar run under a uid inside the chroot which exists as a real account outside the chroot. (Talk to the DBus people.)
Consequently, run something like this both inside and outside the chroot:
groupadd -g 64002 sugar
useradd -m -u 64002 -g sugar sugar
Then, inside the chroot, you can happily run sugar as user 'sugar' with something like
cat > as_person <<EOF
#!/usr/bin/env python
from os import environ, chdir, setgroups, setgid, setuid, execve
from sys import argv
from pwd import getpwnam
user = getpwnam(argv[1])
environ['HOME'] = user.pw_dir
environ['USER'] = user.pw_name
chdir(user.pw_dir)
setgroups([user.pw_gid])
setgid(user.pw_gid)
setuid(user.pw_uid)
execve(argv[2], argv[2:], environ)
EOF
chmod a+x as_person
./as_person sugar /usr/bin/sugar
