Bug 464365

## SUMMARY

I followed [Arch wiki](https://wiki.archlinux.org/title/KDE_Wallet) method to store ssh private key passphrase in kwallet, but when I try to use ssh, I find it asking the password every time despite it being stored in kwallet, and it shows me this error:
```
$ ssh user@example.com
Warning: fallback to QtQuick software backend.
qt.svg: link #path2410 is undefined!
kf.config.core: Created a KConfigGroup on an inaccessible config location "kwalletrc" "Wallet"

Couldn't start kwalletd:  QDBusError("org.freedesktop.DBus.Error.Disconnected", "Not connected to D-Bus server")
Couldn't start kwalletd:  QDBusError("org.freedesktop.DBus.Error.Disconnected", "Not connected to D-Bus server")
Couldn't start kwalletd:  QDBusError("org.freedesktop.DBus.Error.Disconnected", "Not connected to D-Bus server")
Couldn't start kwalletd:  QDBusError("org.freedesktop.DBus.Error.Disconnected", "Not connected to D-Bus server")
Couldn't start kwalletd:  QDBusError("org.freedesktop.DBus.Error.Disconnected", "Not connected to D-Bus server")
Couldn't start kwalletd:  QDBusError("org.freedesktop.DBus.Error.Disconnected", "Not connected to D-Bus server")
```

STEPS TO REPRODUCE
1. Follow the arch wiki link above.
2. Try to use ssh.
3. See `ksshaskpass` asking you for password, for the first time there a "Save password" checkbox.
4. Open a new terminal, use ssh and notice `ksshaskpass` asking for the private key passphrase again, and outputting the warnings above.

OBSERVED RESULT

ksshaskpass fails to connect to kwallet and outputs this error:
```
$ ssh user@example.com
Warning: fallback to QtQuick software backend.

```

EXPECTED RESULT
To get the ssh password from kwallet and pass it to the ssh command for me, so I can have passwordless login flow.
