Hi,
Few days ago I have made upgrade from kde4 to plasma. After update I can't access my old wallet. I think Kmail is using it because I can check my mail (mail accounts passwords are stored in old wallet). When I try to import my old wallet with "Wallet Manager" I get error message with error code -9. And every time I log in there is this pop-up window asking me for my old wallet password but when I type my password this pop-up window just disappears and nothing else happens.
