Ciao Lucio,

That "-sh" is looking weird to me. 

If you look at the source code, those lines should be in the _filedir() function
(marked with *):

_filedir()
{
    local IFS=$'\t\n' xspec

    _expand || return 0

    local toks=( ) tmp
    while read -r tmp; do
        [[ -n $tmp ]] && toks[${#toks[@]}]=$tmp
*   done < <( compgen -d -- "$(quote_readline "$cur")" )
    
    if [[ "$1" != -d ]]; then
        xspec=${1:+"!*.$1"}
        while read -r tmp; do
            [[ -n $tmp ]] && toks[${#toks[@]}]=$tmp
*       done < <( compgen -f -X "$xspec" -- "$(quote_readline "$cur")" )
    fi

    COMPREPLY=( "${COMPREPLY[@]}" "${toks[@]}" )
}


As you can see, that "-sh" is not appearing anywhere.
Did you hack our code? ;) :P

I'm sorry but... well... I just can't reproduce it:

$ pwd
/tmp
$ mkdir bug
$ cd bug/
$ pwd
/tmp/bug
$ touch log; mkdir Maildir
$ cd Mai<TAB>
$ cd Maildir/^C
$ rm -rf Mai<TAB>
$ rm -rf Maildir/^C
$ ls Mai<TAB>
$ ls Maildir/^C
$


My suggestion here is to try reinstalling bash-completion:

# apt-get --reinstall install bash-completion

Hope this helps,
David
