Hmm... I see that, more accurately, it happens in the LPub3D-generated file that is used to display the test model. LPub3D actually applies a rotation to everything in the model. And the numbers that it uses when doing that are rounded to 6 decimal places. I strongly suspect that this rounding is resulting in matrices that aren't quite right, and that factor is causing the texture mapping in LDView to not work.
Trevor, is there any chance you could produce a test LPub3D that uses something silly like 15 decimal places, so we could see if that makes the problem go away? If it does, perhaps that could be a setting in LPub3D.
