customized completion function problem

I've a customized svn completion implemented like this:

complete -o nospace -F svncomp svn
svncomp()
{
    local last dp path=${COMP_WORDS[$COMP_CWORD]}

    case $path in
        */) dp="$path";;
        *) dp=$(dirname "$path")/; last=$(basename "$path");;
    esac

    case "$(eval echo $path)" in
        svn+ssh://*)
            COMPREPLY=( $(compgen -P $dp -C "svn ls $dp" -- "$last" 2>&-) );;
        *)
            COMPREPLY=( $(compgen -f -- "$path") );;
    esac
}

And when i try to complete svn URI, completion command seems to have
problems with gathering the output (probably some sort of timeout,
because only lexicographically first entries are displayed?). In the
following log i just press Tab several times getting different
completion lists.
