How to get back missing Dropbox icon in the Ubuntu panel

I noticed that my dropbox icon went missing due to a bug in Dropbox. To restore it, I came across this post, and at the command line, had to issue following commands after opening a terminal window:

First, install libappindicator1 once by:
$ sudo apt-get install libappindicator1 <enter>

Now, each time, the below commands need to be executed to get the dropbox icon in the panel.
$ dropbox stop -i <enter>
This command will stop the dropbox daemon.

$ dropbox stop &&DBUS_SESSION_BUS_ADDRESS="" dropbox start <enter>
This command starts dropbox and displays the icon in the panel.

Icon came back. This workaround was at

Now, the key command is dropbox stop &&DBUS_SESSION_BUS_ADDRESS=”” dropbox start and you need to enter this each time. Clicking on the dropbox icon in the menus does not work.
