[vtkusers] vtkStreamingDemandDrivenPipeline

[Huisman, H.]

Hi,

Upgraded to a more recent VTK cvs checkout and I start to have messages
like these:

vtkStreamingDemandDrivenPipeline (0x8075e08): The update extent
specified in the information for output port 0 on algorithm
vtkImageMathematics(0x8074b58) is 0 511 0 511 0 79, which is outside the
whole extent 0 511 0 511 0 23.

It use to work fine (so why upgrade? Well eh, new features of course!) 

Somebody experiencing the same thing?  Is there way out?

Thanks,

Henkjan
