Tutorial1::Tutorial1(QObject *parent, const QVariantList &args)
        : Plasma::Wallpaper(parent, args), mutex(new QMutex), blaa(parent, 
mutex, &img)
  img = NULL;
  mutex = new QMutex;

you're assigning mutex twice, once in the ctor init list and once in the body 
of the ctor.

that means that Tutorial1 and Blaa are using separate mutexes, which defeats 
the purpose of having one ;)
