The -depth option is completely broken in GNU find 4.1

Here is a minimal example that will illustrate the bug: run

mkdir /tmp/foo ;
echo Blah > /tmp/foo/bar ;
find /tmp/foo -depth -empty

and the program will respond

find: /tmp/foo: Not a directory

this is evidently bogus.

I have submitted a bug-report to the FSF about this, but since the latest
version of findutils dates from 1994, it is rather dubious that anyone will
ever look into it.

I have written a (trivial) patch of my own that will correct the problem:
it is available at

ftp://quatramaran.ens.fr/pub/madore/misc/findutils-depthbug/findutils-4.1-depthbug.patch

furthermore, there is a source and (Intel) binary RPM that includes this fix:

ftp://quatramaran.ens.fr/pub/madore/misc/findutils-depthbug/findutils-4.1-34.1.src.rpm
ftp://quatramaran.ens.fr/pub/madore/misc/findutils-depthbug/findutils-4.1-34.1.i386.rpm
