Weird bug with cloning paint device

[Cyrille Berger]

Hi,
I have a weird bug when cloning paint device (in koffice 1.5)
Here are the code :

KisAutobrushShape* kas = new KisAutobrushCircleShape(size, size , halfSize, 
halfSize);
    
QImage mask;
kas->createBrush(&mask);
    
KisKernelSP kernel = KisKernel::fromQImage(mask);
    
KisPaintDeviceSP interm = new KisPaintDevice(*src);
    
KisConvolutionPainter painter( interm );
painter.applyMatrix(kernel, rect.x(), rect.y(), rect.width(), rect.height(), 
BORDER_REPEAT);
 
where src is a paint device used in a KisFilter::process(KisPaintDeviceSP src, 
KisPaintDeviceSP dst, KisFilterConfiguration* config, const QRect& rect)

And this doesn't work correctly, the blured result is a little bit wrong, but 
if I do the same thing but with KisConvolutionPainter painter( src ); then 
src contains a correctly blurred paint device.

Anyone has an idea ?
