[bug] strange dark render + indigo connects to internet

I tried to make a testscene for my inverted sss post. The scene rendered ok. I tweaked the scene a little bit. Then my firewall (ZoneAlarm) warned me that indigo wanted to connect to the internet. I denied the request.
After that the render looked very strange. And it happened every time I tried to render again...
BTW: the scene cooked for 15 minutes in 2 threads on a AMD 4200+

attaching the materials didn't seem to work (you canÄt attach .xml, can you?)
so here is the zipped scene with materials

its a simple material test.
a subsurfed cube with sss material on a white phong surface and with sun as light

hmmm
not the materials that worry me, tis the fact that indigo seems to want to connect to the 'net for some reason 0_o

Somebody else had this connection thing before...
I forgot to look at the ip-address, that could have been a help, I think.
EDIT: The black-render seems to be directly related to the use of sss. without it, everything renders fine...

I also got a black render last time i tested SSS (no connection attempts here).
Try it with bidir off.

Putting more focus to the sss issue:
The bug seems to be realted to high sss values. When I reduced the sss value it seemed to work ok.
Also using uniform instead of rgb for sss made everything look more ok (experience from earlier scenes with 0.9t4 not tested with this particular scene, though).
Maybe someone can confirm this for my scene (available in my second post in this thread)? Also could somebody try the effects of bidir on the bug? I don't have indigo installed where I am currently...

hang on, ill dload the scene in a sec and test it out.
BTW i think that u have to let the scene cook even longer,cuz it looks like the floor is highly reflective and that means that the rays have to bounce around longer...(? read that somewhere ?)

nope...
low absorbing stuff causes that.
hireflective doesn't matter.
But a perfect all-colour-at-once-reflecting "white" mirror, is just as "bad" for bounces as a pure white diffuse.
