Inserting QImage in QTextEdit from QMimeData inserts it in wrong colors (only green&white) (perhaps qvariant_cast bug)

Reimplemented insertFromMimeData function of QTextEdit to add possibility to insert images from clipboard(for example, copied from browser). Everything works fine on Qt 4.8.2 and works wrong on Qt 5.0.0 beta.
class CustomTextEdit : public QTextEdit

{...}

void CustomTextEdit::insertFromMimeData(const QMimeData *source)
{
QTextCursor cursor = this->textCursor();
if (source->hasImage())

{ QImage image = qvariant_cast<QImage>(source->imageData()); //image.save("C:/1.jpg"); // here we can see wrong image saved in file // QImage image = source->imageData().value<QImage>(); // gives the same result image.convertToFormat(QImage::Format_ARGB32_Premultiplied); cursor.insertImage(image, "name"); }

else

{ QTextEdit::insertFromMimeData(source); }

}
