Does anyone know what this is? It started to show up after I installed Dropbox I think, and nothing is showing up when I tried to click it. It doesn't change the behavior of my desktop though and the Dropbox folder works fine too. I just want to know what this weird icon is. Thank you!
That is dropbox doing it's recent failing thing. Run this:
dropbox stop && dbus-launch dropbox start
I had the same problem. It's more of a workaround, but it works. It helps to create a custom command to just run that real quick. Create an alias in
alias db='dropbox stop && dbus dropbox-start`
Or, I wrote a script with that in it, then did
sudo install db.sh /path/to/db.sh/commandname
db.sh from the terminal.
