I tried the following commands to fix radiotray, but it is still broken:

sudo apt-get remove radiotray ; sudo rm -rf ~/.local/share/radiotray /usr/share/app-install/icons/radiotray.png /usr/share/app-install/desktop/radiotray:radiotray.desktop /var/cache/apt/archives/radiotray_0.7.3-5ubuntu1_all.deb ; sudo apt-get install radiotray


Here's the output of  find / -name "*radiotray*"
