Not a bug.  Rather than listing the number of files, what ls is really
listing is the number of file system blocks occupied by the files in that
directory (and some files occupy more than one block).

This is required by POSIX:
http://www.opengroup.org/onlinepubs/009695399/utilities/ls.html

| If any of the -l, -g, -n, -o, or -s options is specified,
| each list of files within the directory shall be preceded
| by a status line indicating the number of file system
| blocks occupied by files in the directory in 512-byte
| units, rounded up to the next integral number of units,
| if necessary. In the POSIX locale, the format shall be:
|
| "total %u\n", <number of units in the directory>

Although coreutils takes the approach of 1024-byte units unless you used
- --block-size, or if POSIXLY_CORRECT or BLOCK_SIZE is set in the
environment.  See 'info coreutils "block size"'.

You may want to consider upgrading.  The latest stable version of
coreutils is 6.9.
