Undo operation on .stl causes segmentation fault.

[GoogleCodeExporter]

open a .stl file.  The blender default cube is attached.
Select the cube.  Using the handles, drag or scale the cube to a new location.

Click the red 'undo' button.  

Heekscad crashes.

This doesn't happen using a heekscad solid.

This hasn't been a priority for me because I don't use STLs very much.  The 
reprap folks use stls a lot and I found another report of this problem on this 
blog:

.html

Some additional details that might be useful to someone:

"Hmm your right, the STL is the issue, but here's the funny part. Deleting the 
STL out of the files does not help, and if I copy components out of the drawing 
and save it into a non stl document, the behavior follows the pasted parts, 
even though no STL had been loaded into that document. Really odd stuff, but at 
least now I know how to aviod the crashing issue. "

I fixed this. STL objects weren't copying their ID values for the undo engine.

How do I fix this in my copy of Heekscad, do I have to wait for the next 
version?

Yes. It's about time I made another Windows installation.
