.blend files not anymore convertable?

Update jMonkeyPlatform just a minute ago

I put a not compressed blend (with Susanne) in the Models directory

Trying to convert gives error:

OGL: Waiting for re-init authorization…

EDT: Acknowledged receipt of re-init request!

Invalid structure name caused by invalid table length: null

Error occured while loading resource Models/monkey1.blend using BlenderModelLoader

Trying to save asset that has not been loaded before or does not support saving!

Could not locate saved file.

Meaning that I do not know, how to handle.

Please explain …

The suggested way of importing models is exporting via OgreXML from blender and then importing the OgreXML files. The blender loader is very experimental still.
