Problem 431

I have geant4 code for simulation the transport of optical photons in big
scintillator detector. It worked perfectly well with geant4.3.2 version.
	Now I moved to the new geant4.4.1 release and tried to use my code with
this new geant4.4.1 release. And obtained some new diagnostics:

	Warning ... PCone not able to return normal ..

	This occurs approximately in 10% cases of each photon tracking:
For 12000 of simulated photons I obtain 1430 warnings.

	To describe the detector LightGuides I use G4BREPPolycones.

	The same bug I had seen in the report number 425.
	I would like to emphasize that my program worked well with 4.3.2 release,
while the same program in new 4.4.1 release (which supposed to be better)  gives
this huge amount of warnings.

	Best regards. Igor Matchouline.
