Another stack trace from HEAD (1119860)

I think I fixed the bug in HEAD and was able to test this bug again.

In the code below, d is NULL after the setPreviewImage call. d is ok before the
call. 

void AdjustLevelsTool::putPreviewData()
{
    DImg preview = filter()->getTargetImage();
    d->previewWidget->setPreviewImage(preview);

    // Update histogram.

    if (d &&(d->destinationPreviewData))
       delete [] d->destinationPreviewData;

    d->destinationPreviewData = preview.copyBits();
   
d->gboxSettings->histogramBox()->histogram()->updateData(d->destinationPreviewData,
                                                             preview.width(),
preview.height(), preview.sixteenBit(),
                                                             0, 0, 0, false);
}
