[Paraview] another error message using custom reader

[John Biddiscombe (CSCS)]

I'm using today's cvs (but I've tried with several versions), and I have 
a new error. the reader generates a heirarchical box dataset with a 
single uniform grid inside it. The reader reads data ok and pumps out 
some info for me for debugging, but once it finishes the executedata 
method, the error below pops up.  I'm not sure where to look for this 
vtkMPIMoveData data problem. If anyone can point me in the correct 
direction, please do...

incidentally, notice that the update extent of the box is 0,-1.... which 
is what I'd expect on first pass, because the pipeline doesn't know how 
big the data is until  executeinformation has generated the size, but 
once we get to execute data I would expect the streaming mechanism to 
have puit something in there. I'm hoping to run the file reader on 8 
nodes and break the file read up between them. Do the heiracrchical box  
datasts handle extents the same as structured data...

anyway..thanks in advance for any clues
