Will it work if you remove the "Clowns" and "MurrinaNightOrange" -folders? rm -rf /opt/plastic-schemes/Clowns rm -rf /opt/plastic-schemes/MurrinaNightOrange Edit: seems like the package murrinanightorange doesn't include about any theme elements, so it' clearly a broken package. Removing the direcotry /opt/plastic-schemes/MurrinaNightOrange should do the trick.
