Strange output from find
How can I prevent find from outputting the directory name /home/xxxxxxxx/Backup/.system (which isn't even "other writable"?

I am trying to search for files that are "world writable" on a shared web host using the find statement, and I want to prevent find from creating an error (because the of directory permissions). I don't want to just pipe stderr to /dev/null as this would suppress unexpected errors.

This statement works correctly but produces an error"
Code:
# find /home/xxxxxxxx  -type f -perm -o+w
find: `/home/xxxxxxxx/Backup/.system': Permission denied

but for some reason the statement
Code:
find /home/xxxxxxxx -type d \( -iwholename "/home/xxxxxxxx/Backup/.system" \) -prune -o -type f -perm -o+w

creates the output
Code:
/home/xxxxxxxx/Backup/.system

i.e. it outputs the name of the directory excluded along with the files that are "other" writeable.

FYI
Code:
# ls -laR /home/xxxxxxxx/Backup/
/home/xxxxxxxx/Backup/:
total 12
drwxr-xr-x  3 xxxxxxxx xxxxxxxx 4096 Feb 15  2011 ./
drwx--x--- 31 xxxxxxxx nobody   4096 Aug 12 14:43 ../
drwx--x---  4 root     xxxxxxxx 4096 Feb 15  2011 .system/
/bin/ls: cannot open directory /home/xxxxxxxx/Backup/.system: Permission denied

the W bit is not set for "other", so I don't understand what is going on.
I am using find (GNU findutils) 4.4.2 on CentOS in case it matters.

How can I prevent find from outputting the directory name /home/xxxxxxxx/Backup/.system (which isn't even "world writable"?

As an aside, has anyone seen a good find tutorial? Man page does an OK job with the individual options, but really lacks the context for putting them together in combination

createhomedir

createhomedir(1)					    BSD General Commands Manual 					  createhomedir(1)

NAME

     createhomedir -- create and populate home directories on the local computer.

SYNOPSIS

     createhomedir [-scbalh] [-n directoryDomainName] [-u username]

DESCRIPTION

     createhomedir provides several options for creating and populating home directories.

OPTIONS

     -s       creates home directories for server home paths only (default).

     -c       creates home directories for local home paths only.

     -b       creates home directories for both server and local home paths.

     -a       creates home directories for users defined in all directory domains of the server's search path.

     -l       creates home directories for users defined in the local directory domain.

     -L       causes the created home directory to be localized.

     -n directoryDomainName
	      creates home directories for users defined in a specific directory domain in the server's search path.

     -u username
	      creates a home directory for a specific user defined in the domain(s) identified in the -a, -l, or -n parameter. If you omit the -a,
	      -l, and -n parameters when you use the -u parameter, -a is assumed.

     -i       reads username list from standard input and creates specified home directories. Each username should be on its own line.

     -h       usage help.

FILES

     /usr/sbin/createhomedir			   location of tool

CAVEATS

     When using the -a option, search limits of various directory servers (such as Open Directory or Active Directory) can prevent all possible
     home directories from being created. In this case, you may need to specify the usernames explicitly.
