Blender import "crash".

This error just started happening after 4.5.1f3 update. For some reason everytime I save my model in blender and import to Unity, Unity shows an error saying that “Blender has crashed and must close” but blender never actually closes. Unity then shows that “Blender could not convert the .blend file to FBX file”.

Unity Version - 4.5.1f3
Blender Version - 2.71
