Q:

Why is the Tomboy Note indicator icon duplicating itself?

I have a bug with Tomboy Notes application on Ubuntu 14.04 LTS.
Whenever I boot my system, clicking the original panel, the icon doubles. And every word that I type and delete in the search bar, the icon also doubles.
Another problem, when you click to create new note it appears an error of "Broken" pipe. When I click the icon again, I see that the note was created empty, with current date and time.
Look at the video.

A:

The duplication of Tomboy indicator icons is a bug caused by unity-tomboy-lens, which is a lens that allowed for searching the contents of Tomboy notes via the Dash in 13.04. There were some issues in 13.10, but overall it still worked; in 14.04, however, it totally ceased to display the notes in the dash, plus caused this bug.
Unfortunately, the developer seems to have stopped using Unity, so the lens will doubtfully be updated (see this bug report).
