Floating point exceptions

Since integrating Paged Geometry in my simulation I'm getting lots of seemingly random floating point exceptions that crash the programme during runtime after the paged geometry has been loaded.

I'm running on Ubuntu linux. Any ideas? Is there any way of tracking down what might be causing this - perhaps something to do with the meshes that I'm loading?

Cheers

I'm using the 1.05 release.
I also can't get the imposters to run - it crashes on load so I've just disabled them. The examples compiled and ran properly so I'm assuming it's a problem with my scenery meshes.
