Same for me. I only have 3DCORECTMESH types and none of my data loads. 
Time is good, but geometry is lost.

ImageData is the only datatype afaik that paraview takes all 
origin/spacing/extent information directly from the information object 
attached to the data, rather than the data itself. I suspect that the 
information being set insiside RequestGridInformation in the xdmf 
reader, is being set on the grid's individual information, object, but 
not being copied into the output information. I'm looking into it.
