Comment 174 for bug 1026426

I experienced the same as Martin Wildam. Two days ago I upgraded from Ubuntu 12.04 LTS to 14.04 LTS. Many month ago I edited the Quicklist of the LO Writer-Icon using Ubuntu Tweak. This action resulted in a file named libreoffice-writer.desktop in ~/.local/share/applications. After upgrading to Ubuntu 14.04 LTS this file was used again and I faced the problem with double icons of Writer in the Launcher. I deleted the file named libreoffice-writer.desktop in ~/.local/share/applications. Now I have always only one icon of Writer in the Launcher because Ubuntu now uses the original file in /usr/share/applications.

In short: The problem occurs maybe when the file named libreoffice-writer.desktop in ~/.local/share/applications was edited manually and therefor is not compatible anymore.
