Nope.  ParaView is just telling you that the current operation is not supported.

Probably the best course of action is to submit a feature request to ParaView's bug list (http://www.paraview.org/Bug) to which you can attach an example file.  I would also recommend entering the feature in uservoice (http://paraview.uservoice.com/forums/11350-general).  The ParaView developers use this site to determine the priority of suggested features.

If you have an example data set that is not too big, you can email it to the mailing list or directly to me and I can do these for you.

Up to now I have been working with version 3.2.  I just installed
version 3.8 to see if there were any differences in behavior.

In version 3.8 I'm not allowed to do volume rendering at all.  When I
try to set the "Volume" representation option (which resulted in display
of a black block in 3.2), I now get an error message that says "Cannot
volume render since no point (or cell) data available."

Has the volume-rendering-of-image-data feature been excised from version
