One way to test this ticket:

1. Load an MDEvent workspace (I used ImportMDEventWorkspace) (MD)
2. Use slice viewer, choose an appropriate slice, and visualize it using number of events normalization (MD_rebinned)
3. Clone the MD_rebinned workspace using CloneMD to MD_clone
4. In python, run the following

   w=workspace('MD_rebinned')
   cl=workspace('MD_clone')
   cl.setSignalArray(w.getSignalArray()/w.getNumEventsArray())
   

The slice for MD_rebinned with number of event normalization should look like the slice for MD_clone with no normalization

This looks to be working properly.
