How to unlock Kwalletmanager KDE4 with kwalletmanager5 KDE5?

I am a little lost with kwalletmanager5. I upgraded my system from OpenSuseLEAP42.1 to OpenSuseLEAP42.2 a couple of months ago. With KDE5. Since I updated my system I have problems with the kwalletmanager, or better the interplay of kwalletmanager5 and the KDE4 version of kwalletmanager. > kwalletmanager --version Qt: 4.8.6 KDE: 4.14.28 KDE Wallet Manager: 2.0 > kwalletmanager5 --version kwalletmanager5 16.12.1 > kwalletd --version Qt: 4.8.6 KDE: 4.14.28 KDE-Dienst für Passwortspeicher: 0.2 The main problem I encountered was that the new kwalletmanager5 does not accept a GPG key to encrypt the wallet. This is a problem since I used GPG in KDE4. Now, each time I open the kwalletmanager5, I have to enter first the password for kwalletmanager5 and then for kwalletmanager4. So I tried to uninstall the KDE4 version of kwalletmanager. Which caused problems with some other applications... Somewhere I read that you need to have installed both versions so that KDE4 applications can use kwalletmanager and KDE5 applications kwalletmanager5. All in all, I have two questions: 1. Is there a way to unlock kwalletmanager with kwalletmanager5? 2. I would like to use GPG-encryption with kwalletmanager5. Is there a way?
