I don't know why I had trouble yesterday, but as Berk says, it should be 
vtkDataObject as input not vtkTemporalDataset - and when I put this in, 
I was able to do particle tracing on a volume (vtkImageData) dataset. 
(Didn't try the LEA one, but it's safe to assume it'll work).

For those that care - vtkTemporalDataset should not generally be 
imported directly by a filter, instead the filter should request 
multiple time steps and let the executive create the temporal wrapper. 
We have one use case (referred to in my xdmf post which causes trouble, 
but we'll fix that eventually).
