Additional information

• I noticed that ~/.local, ~/.local/share and ~/.local/share/kwalletd belong to user:root instead of user:user. Is this correct?
• I've tried to re-apply the kwallet fix. After that, the kwallet dialog does not show up anymore. Instead, I'm asked for the WIFI password after every reboot.
