FindShapes has NaN axis Euler angle in specific cases

Occasionally, FindShapes gives a NaN axis Euler angle output. This happens when `uberbelim[elimcount - 1][0]` becomes a NaN value due to `uberelim[elimcount - 1][elimcount - 1]` being zero.

In my case, the NaN values occur when the calculated moments of a specific grain are Ixx=4.5, Iyy=3.5=Izz=3.5, Ixy=Iyz=Ixz=-1, and the resulting `uber` matrix for `j=1` is {{0, -1, -1}, {-1, -1, -1}{-1, -1, -1}}. Here is a picture of this "failed" grain for what is worth:

I'm not sure what the true root cause of this is, though.
