I had some sporadic GPF's with this but mostly some realy odd behaviour on 
the import.

What happened is that when I exported an object with refrences to a CSG with 
the 'no export' flag, these references got replaced with the same name 
object in a new scene.

Here are the steps to reproduce:

1) Create a model, do some moderatly complex CSG and grouping.
2) Don't change any CSG or group names.  Create some references to other 
objects.
3) Make a big copy of your original obecject.
4) On the ORIGINAL uncheck the box that says 'export'
5) Save the parent COPY object as an 'object' (this will create an MDL file)
6) Create a new file.  Add some new objects, with CSG and grouping.
7) Don't change any CSG or group names.  Create some references to other 
objects.
8) Import (Merge) the model you saved in 5.

What will happen is that the CSG001 in the original will now 'link' to the 
CGS001 in the new scene.

This really, really looks odd.  It may or may not be related to the 'export' 
flag, it might be because I saved an object with references to objects that 
I didn't save.

Did that make any sense?
