Hmm, I do not know exactly what to change here, as searching through the code
shows it is almost always used like that, if there are no options - this is from
wall.cpp for example:

    CompOption::Vector o(0);
...
...
    screen->handleCompizEvent ("wall", "start_viewport_switch", o);

I am quite clueless here, but the version we use seems correct...
