integration scan_range does not work

[dagewa]

Set up:

dials.import $(dials.data get -q centroid_test_data)/*.cbf
dials.find_spots imported.expt
dials.index imported.expt strong.refl
dials.refine indexed.expt indexed.refl

Now this works:

dials.integrate refined.expt refined.refl

and correctly does scan-varying prediction:

Prediction type: scan varying crystal prediction
Predicted 4503 reflections
Matching reference spots with predicted reflections
 376 observed reflections input
 4503 reflections predicted
 376 reflections matched
 376 reflections accepted

but this fails:

dials.integrate refined.expt refined.refl scan_range=2,8

with

Prediction type: scan static prediction
Predicted 3607 reflections
Matching reference spots with predicted reflections
 376 observed reflections input
 3607 reflections predicted
 362 reflections matched
 0 reflections accepted
Sorry: 
          Invalid input for reference reflections.
          Zero reference spots were matched to predictions

This also does not work:

dials.slice_sweep refined.expt refined.refl image_range=2,8
dials.integrate refined_2_8.expt refined_2_8.refl

...

Prediction type: scan static prediction
Predicted 3831 reflections
