[Paraview] segfault opening the color scale editor / vtkPVProminentValuesInformation?

[Burlen Loring]

with git 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?

Program received signal SIGSEGV, Segmentation fault.
