</div>Tutorial1::Tutorial1(QObject *parent, const QVariantList &args)<br>
: Plasma::Wallpaper(parent, args), mutex(new QMutex), blaa(parent,<br>
mutex, &img)<br>
{<br>
img = NULL;<br>
mutex = new QMutex;<br>
<br>
you're assigning mutex twice, once in the ctor init list and once in the body<br>
of the ctor.<br>
<br>
that means that Tutorial1 and Blaa are using separate mutexes, which defeats<br>
the purpose of having one ;)<br>
