Ok. I changed light to point and increased its strenhgt. Its working. Still I dont understand why sun does not work with volumes like such domain. I understand why it doesnt work with world volume (pretty reasonable -light at infinite distance and volumetric world) but why doesnt it work here? Volume domain has its thickness, and it should be considered in all calculations. Why is the sunlight in this case???

@Thomas Dinges (dingto) This is bug due to any type of light in this case. I dont use sun lamps. World has no volumetrics. Please download my .blend file and test it. Volume Bounces settings make no differences.

"No direct light" I mean "no direct light" noticeable still in render.
Sorry for flooding.

Thank you ace_dragon.
Yes, simplified scene reproduces same bug. Just connect a volume scatter shader to default cube (default scene), removing diffuse one. No direct light. Lamp size makes no difference.
Blender 2.71 render is all fine, later versions are not.
