Hello,

Lock does not work anymore on XFCE 4.20, after moving from 4.18.

When I try to run the command manually via the terminal on XFCE 4.20, this is what I get:

```console

$ xflock4
/gnu/store/yz669dvm1cm9nqcxkm8hq8zzgf0cy96f-profile/bin/xflock4: line 52: gdbus: command not found

```

This must be because of the introduction of commit 42db188a somewhere around 4.19, making xflock4 dependent on D-Bus.

Regards,

Ashvith
