It does run with a GUI, but the only UI elements it has are those
rendered by the kwallet service (things like the unlock prompt);
it requires a GUI display even if itself only uses stdio and command
line arguments.

Search for openWallet there.

The window ID was added by the person who ported this to KDE 5;
apparently, this is necessary now.
