A correção está no primeiro comentário :
Do this: rm -Rf ~/.local/share/docky/plugins
Then start Docky.
Estou usando o Dockpa ppa e, desde a última atualização, não será iniciado. Se eu correr do terminal, é isso que eu recebo:

E isso .Skip () continua infinitamente e muito rápido. Eu tentei limpar o cache e reinstalar o docky, mas sem sorte.
