Expected Results: Clipboard should be cleared everywhere. Keepassx version 2.0.2
I'm sorry, but that is just not possible from a technical point of view. In the days before becoming the maintainer of klipper and understanding how this technically works I reported a similar bug 156547. Technically that's just not possible. We don't get a signal "don't save this password", we just get a "hey the new clipboard content is an empty string". We don't have any meta information about the clipboard content. We don't know that it is a password, we don't know which application send it, and so on.
