Which shell you are testing, ash or hush?

Did you try it in bash? It also "fails" there. This is just how it should work
in this case.
You can use:
for i in "`find .`"
but this will jam *all* filenames into one $i. So probably:
find . | while read filename; do ...; done


Try this script:

#!/bin/sh
testing() {
        echo "Testing $1"
        rm -rf dir 2>/dev/null
        mkdir dir
        >"dir/a b"
        echo "Test with find"
        $1 -c 'for i in `find dir`; do echo $i; done'
        echo "Test with ls"
        $1 -c 'for i in `ls dir/a*`; do echo $i; done'
        echo
}
testing "bash"
testing "./busybox ash"
testing "./busybox hush"


It outputs:

Testing bash
Test with find
dir
dir/a
b
Test with ls
dir/a
b

Testing ./busybox ash
Test with find
dir
dir/a
b
Test with ls
dir/a
b

Testing ./busybox hush
Test with find
dir
dir/a
b
Test with ls
dir/a
b


as you see, both busybox shells are compatible with bash in this regard.
