I have been plagued by this problem for monthes now. I don't have a
solution, but here is a bash shell script that will reproduce the
problem. It is checking every file in its argument list. It is most
likely to cause the problem when presented with a long argument list.
I like to exercise it by launching it from C:\Windows as
	undupe.sh *

Here is undupe.sh:
#!/bin/bash

if [ $# -eq 0 ]
then
	echo "Usage: undupe.sh files..."
	exit 1
fi

declare -i first
declare -i n_dup
((n_dup = 0))
echo "Will process $# files..."

while [ $# -gt 1 ]
do
    left=$1
    if [ -f "$left" ]
    then
	((first = 1))
	for right in "$@"
	do
	    if [ $first -eq 1 ]
	    then
	        ((first = 0))
	    else
		if [ -f "$right" ]
		then
		    cmp -s "$left" "$right"
		    if [ $? -eq 0 ]
		    then
			echo "$right" is the same as "$left"
			((n_dup = n_dup + 1))
		    fi
		fi
	    fi
	done
    fi
    shift
done

echo "Deleted $n_dup files"
