Actually the GConf change predates squeeze. The packages that still had
them in squeeze had just not been updated since the change.

Since squeeze, this snippet does absolutely nothing. The first thing
gconf-schemas does is checking whether it is called from such a script,
and if it is, it just does sys.exit(0). Everything is done by the
