Dropbox Icon Notification Area red circle with diag like Ghostbusters

I installed ChaletOS 16.04 on my DELL Inspiron 5559 laptop.

Code:

hugh@DELL-V-CHALETOS:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04 LTS
Release: 16.04
Codename: xenial
hugh@DELL-V-CHALETOS:~$

Code:

hugh@DELL-V-CHALETOS:~$ echo $XDG_CURRENT_DESKTOP
XFCE
hugh@DELL-V-CHALETOS:~$

I installed Dropbox but getting the dreaded Dropbox Icon which is red circle with cross like Ghostbusters, I tried a fix that I found and used in other distros ...

Code:

$ dropbox stop && dbus-launch dropbox start

this fixed the Dropbox icon, but I got some strange messages which indicates this may not be the best solution....

Code:

hugh@DELL-V-CHALETOS:~$ dropbox stop && dbus-launch dropbox start
Dropbox isn't responding!
Dropbox isn't responding!
Dropbox is already running!
hugh@DELL-V-CHALETOS:~$ dropbox stop && dbus-launch dropbox start

Done!
hugh@DELL-V-CHALETOS:~$

the Dropbox icon did display correctly but after reboot, the icon error returns

I also tried this alternative command...

Code:

$ dropbox stop && DBUS_SESSION_BUS_ADDRESS="" dropbox start

again, this fixed the Dropbox icon, but I get similar messages...

Code:

hugh@DELL-V-CHALETOS:~$ dropbox stop && DBUS_SESSION_BUS_ADDRESS="" dropbox start
Dropbox daemon stopped.

Does anyone know best way to fix this? I'm quite new to linux and not sure how to proceed,

NOTE FOR DEVELOPERS: I was led to believe that the errors I received were related to the theme that I am using (ChaletOS_Default). It may have some errors in it.

I'm just posting to let the developers know in case there is a problem and also trying to find out how to fix the Dropbox icon error.
