I didn't know that flushClipboard is called for simple text edit fields for C'n'P operations, and not just on LO shutdown. This way the simple text is actually secured in the clipboard instandly, as there aren't complex mime-types to generate and secure. As a result we also need to protect flushClipboard from loosing ownership, which wasn't needed for the shutdown-only case, as this would give up ownership anyway.
