I had a similar problem, some time ago, and if I remeber correctly the problem
was that the parent of graphicWidget() was 0. Try to change "topLevelWidget =
new QGraphicsWidget;" with "topLevelWidget = new QGraphicsWidget(this);".
On a side note it is better to instantiate those pointers in this way:
SifyClient::SifyClient(QObject *parent, const QVariantList &args)
: Plasma::PopupApplet(parent, args),
topLevelWidget(new QGraphicsWidget(this)),
...
