To reproduce this problem:
* Select a project containing large meshes
* Display a geometry node
* Explode it into faces
* Click on a face in 3D view
Then all amibe*.dir/jcae3d files are scanned, which may produce OOM errors when files are large.
Same happens when first clicking on a face and then explode shape into faces.

AFAICT these files should not be scanned unless operations on mesh nodes are performed.

Should be fixed in the subversion repository but more tests are needed.

Fixed in jCAE 0.16. Now only opened geometry files are scanned while picking.
