With 'set dbus-service false' in zathurarc the dbus service should not be used.
However, even with this setting set to false, we have an open file descriptor to the dbus socket in '/run/user/UID/bus'
The setting disables the SyncTeX forwarding but seems to still initialize the dbus service connection.
This is relevant when using the strict sandbox setting, as the open socket connection to dbus is an easy way of sandbox escape. Since we dont need this connection when the dbus-service is set to false (or when using the strict sandbox) we shoudl be able to avoid initializing this connection.
Im not quite sure where this initialization happens though
