Unmount the filesystem comtaining the problem home directory and check the permissions of the mount point directory - check you have at least "x" permission for the user you are trying to connect with FTP.

Apparently BSD UNIX protocols check the underlying mount point permissions as well as what you can see when the filesystem is mounted, if you don't have at least "x" permission, things give errors like this.

It's a good idea to have no access to the mount point to create files by accident in what will be a hidden directory, covered by the mounted filesystem, and a "chmod 111 /mount/point" may be the best recommendation for permissions.
