Unknown length means that this packet uses partial length encoding
because it does not know the length in advance and gpg always works in
stream mode.

It is not a problem, it is just a standard encoding.

You used the --textmode option to create the file and thus we hit this

        /* Because the text_filter modifies the length of the
         * data, it is not possible to know the used length
         * without a double read of the file - to avoid that
         * we simple use partial length packets. */
        if ( ptmode == 't' )
	  filesize = 0;



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
