Steps to reproduce:<br>
<br>
Start pvserver running parallel 2 ranks<br>
Open the attached dataset, load b array<br>
Slice the dataset such that the slice contains no data from at
least one rank.<br>
Color slice by b array magnitude (default)<br>
Open the color scale editor -> crash<br>
<br>
I added the test dataset to the bug report:

master from this afternoon, I'm experiencing segfaults when I try
to open the color scale editor. seems to be related to
vtkPVProminentValuesInformation. As soon as I get 4 or more ranks
I have the segfault. Is this a known issue?
