You don't fix it in Poser. You need the free UVmapper program to fix the out-of-range UV coordinates. There is a free version for both MAC and PC.

Spanky's freeware STOMP is another great obj tool. It optimzes the OBJ (cleans up the code). (PC only though)

imho, Running an obj through UVmapper and STOMP is always a good idea. Maybe that could be included in the troubleshooting tips?

byw, I tried to replicate the Koji head import crash, but I was unable to crash FaceShop this time. ^^;;;;
