My guess would be that vertices aren't welded along the edges. I can see it happening with the latch portion too. Since it sounds like you've checked that, I'd look and see if it isn't somehow becoming split in the export/import process, perhaps something to do with the seams because it is following those.

My other thing would be to try turning off the smooth polygons in Poser.

Do you mean to turn Smooth Polygons in the Render Settings checkbox?  Or on the object, or both?  I tried unchecking it in render settings.  The edges don't tear- but now they aren't rounded at all.
