[Paraview] colormap for logarithmic quantities

[John Doe]

When I try to view a color map logarithmically, I get the following error:
ERROR: In /home/berk/Work/ReleaseBuilds/ParaView3/VTK/Common/vtkLookupTable.cxx,
line 120
vtkLookupTable (0x8ff2ae0): Bad table range for log scale: [-1e+15,
9.999e+18], adjusting to [1, 10]

Would it be reasonable to request that the log option for the colormap
takes the absolute value of the quantity for which the log is taken?

Thanks,

Juan
