Here is all I managed to render before POV threw an exception. The main 
figure is a mesh. It has a reflective finish, absorbing media, a 
max_trace_level of 31, 7 dispersion samples, focal blur, and 2182 
spheres inside the mesh...

This also happened when I was testing the opal. It seems to have 
something to do with having lots of transparent objects inside another 
object.

I wonder if I should write up a bug report?

You should. :-)

It appears odd to me that this should happen with comparatively few (as 
it would seem to me) nested transparent objects.

This is an entirely off-topic, irrelevant comment, but...

It appears that your dialog box image was cropped from a larger image, 
presumably the whole screen.  While the PrintScreen key will save the 
entire screen, you can also use Alt-PrintScreen to save just the 
currently active window -- no cropping necessary.

I _think_ it's Alt-PS, but it might be Ctrl-PS -- I'm using Linux at the 
moment and don't want to bother rebooting to Windows to double check.

You're remembering perfectly right - but as Alt-PringScreen only 
screenshots a single window, it wouldn't have allowed to capture both 
the rendering preview /and/ the error box.

I think we would have missed a fascinating (albeit partial) pictute.

Thanks Larry! I had no idea about that, or else I would have used it.

RIGHT-ALT & PrtScreen, else Windows might pop up a dialogue to enhance 
screen-contrast for the visually challenged.

Well, it looked to me that it was two separate screen captures that were 
pasted together, which prompted my comment.  Or more likely, the image 
was from the saved file and not a screen capture.

Agreed!

The latter seems pretty unlikely, given that POV-Ray 3.7 at present 
doesn't write images to file until render has completed :-)

That pretty likely depends on Windows version and/or settings. On my 
Windows XP x64, either Alt key will do the job (even though I use German 
keyboard settings, where the right Alt key generally does different 
things than the left one, and is actually labelled "AltGr").

Technically, it does ;) The povstate file ... :)
