Summary:
As stated in the wiki https://wiki.x2go.org/doku.php/wiki:advanced:nx-keyboard-shortcuts
The action "close_session" should terminate the session.
But, pressing Ctrl-Alt-t in a "local desktop" session does not "terminate" the session.


Steps to reproduce:
0. Create a new session profile in x2goclient with session type "Connect to local desktop";
1. Connect to remote computer using this session profile;
2. Press Ctrl-Alt-t at the client.

Expected behaviour:
The remote desktop window on the client should close, the connection should be terminated.

Actual behaviour:
The remote desktop window on the client does not close, the connection is not terminated.
The following log entries appears in the server's system journal:

```
