History has access to the password generator
While fields in the history are read-only (with a little inconsistence that the Notice-field changes the mouse cursor while the other input fields doesn't) it is possible to open the password generator and generate visually a new password.
This change seems to have caused the password generator menu option to disappear if no database is open. At least, it's the only related change I could find in the changelog. Since I only use KeePassX for generating passwords and then store those in gnome-keyring, this breaks the application for me.
