secret-service library interferes with kwallet on KDE without GNOME keyring installed, since kwallet offers org.freedesktop.secrets

[purejava]

I analyzed cryptomator/cryptomator#3476 and was wondering why the user has this issue, although Cryptomator worked on my EndevourOS.

The bottom line is, that kwallet offers a secret service interface for some time now. So on a freshly installed KDE without GNOME keyring installed, you have the following D-Bus service available:

That's exactly the one secret-service checks for on startup and GNOME keyring is available from then on as a keychain back end.

The user's problem resulted from the combination of configuring GNOME keyring as the password back end in Cryptomator, but not having a default KDE wallet.

Once you have a default KDE wallet (which is created from KDE, when you first try to save a secret or manually created or kdewallet does it for you), you can even use secret-service and kdewallet interchangeably to save passwords to kwallet and read them from there. The following screenshot shows the result when having two vaults:

I did not test every feature, but as far as I can see, this works flawlessly. However, secret-service using kwallet does not trigger kwallet to create a default KDE wallet, in case it does not exist and that leads to many ugly exceptions in Cryptomator.
