The method is Gnome2::GConf::Client::remove_dir.

But I actually don't think that those methods actually do what you think
they actually do.

Ehr...

Okay, let's start again.  Gnome2::GConf::Client::unset does *not* delete
a key from the GConf database: it merely puts it in an "unset" state -
which will result in having the value fetched from the default value (if
any) specified in the attached schema (if any).

Gnome2::GConf::Client::remove_dir removes a GConf "directory" from the
list of the watched directories - it does *not* remove the directory
from the GConf database.

The only way to actually delete a directory would be to use the
Gnome2::GConf::Engine::remove_dir method - but you should never ever do
this, under any circumstances, unless you really know what you're doing.
And unless you say "klaatu barada nikto" while you're doing it,
otherwise things could get really messy.

[ Just looking at the code, anyway, it seems that no check is performed
on the owner of the engine, so it could be possible to get away with it
- but it's not guaranteed to work now or in the future.]

 Emmanuele.
