Looks like a bug in plasma ;-)

QGraphicsTextItem does not have setDefaultText... However, the text
color is changed when I use the QGraphicsTextItem setPlainText/setHtml
so I believe this is a plasma bug. However, I'm unable to check since I
don't have it on my machine :( "going to do something about that :)"

Here is what I used to reproduce the behavior:
#include <QtGui>

int main ( int argc, char **argv )
{
    QApplication app(argc, argv);

    QGraphicsScene scene;

    QGraphicsTextItem item;
    item.setTextInteractionFlags(Qt::TextSelectableByMouse);
    item.setDefaultTextColor(Qt::red);
    item.setPlainText("Hello World");
    //item.setHtml("Hello World Html");
    item.setPos(0,0);

    scene.addItem(&item);

    QGraphicsView view;
    view.setScene(&scene);

    view.show();

    return app.exec();


}
