The scene below gives incorrect (ultra-grainy) results. It doesn't happen
when using a regular camera. Changing the tolerance value doesn't help.
Altering the position of the points can remove the problem in some cases.

Tested with the current official Windows binaries, Windows XP HE (P4 1.7 Gz,
1 Go RAM), but was reported first on another system.
