I get the same behaviour:

=====
$ sudo rm /etc/sbuild/chroot/unstable-amd64-sbuild
rm: cannot remove '/etc/sbuild/chroot/unstable-amd64-sbuild': No such file or directory

$ sudo rm -r /srv/chroot/unstable-amd64-sbuild/
rm: cannot remove '/srv/chroot/unstable-amd64-sbuild/': No such file or directory

$ sudo sbuild-createchroot unstable /srv/chroot/unstable-amd64-sbuild/ http://httpredir.debian.org/debian/
chroot with name unstable-amd64-sbuild already exists at /usr/sbin/sbuild-createchroot line 214, <$pipe> line 1.

The bug in the above behaviour is:

* The obvious filesystem entries where the chroot might “already
  exist” do not actually exist, yet the tool refuses with the above
  message anyway.

* The user needs to make a decision about how to resolve the problem,
  but the message gives no help in finding what problematic thing
  “already exists”.

Both those, IMO, need to be correct to resolve this bug.
