Duplicated Libreoffice icon in Unity Launcher

[Roberto González Correa]

I do an intensive use to Libreoffice in Ubuntu, in particular, Writer and Math. Today, I opened Writer by clicking the corresponding icon in the Unity Launcher, and went to Recent Documents to open a file I was working on, when I noticed that there were two Writer icons on the Launcher, as the attached screenshot shows. The upper icon remained 'blinking', as indicating the application was starting, while the the other icon remained highlighted, and let me control the application window.
Surprised, closed Writer and the lower icon disappeared, but the other one was still blinking.
This issue remember me Bug #1063862 and Bug #842566 , both related to BAMF and supposedly fixed on Quantal and Precise.

Did it reappear on Raring?

Regards.

Roberto.
