I appear to have hit a transparent blob bug.

I initially though the bug was related to task 53, which it is noted is 
fixed in the latest beta but the scene I trying to render will still not 
render a specific part of the scene given reasonable time, i.e. 18 hours 
just for one specific square (bucket?), when in MacMegaPov 1.2.1 the 
whole scene renders in 8 hours. Using non transparent spheres in the 
blob it renders in seconds in either version.

The scene is rather large, well for me, with over 5000 spheres 
contributing to the blob so I know its not ideal for debugging other 
than the 'start it off in, a debugger and wait a day and see where its 
at and them start debugging' style.

I'm currently rendering it again, in order to locate the spot it stops 
again and seeing if a partial render of that area with allow for a 
quicker run to the point it stops.

The system specs are...
2.0Ghz CoreDuo 2Gb iMac, running OSX 10.6.2

The version of POV-ray I'm running is the Yvo's 3.7.0.beta.35 Universal 
build for Mac OS 10.5 or later.


Persistence of Vision(tm) Ray Tracer Version 3.7.0.beta.35
Compiler: gcc 4.2.1 (Apple Inc. build 5646) (dot 1)
This is an unofficial version compiled by:


The scene can be downloaded from 
http://planetgenesis.sf.net/blob_bug.zip and is 133kb
