The issue seem to be related to a properties view not disabled after closing a Review group, 
so if the properties view is updated with new text while no review group is opened, the NPE will happen, 

the code was modified to include additional information during the checkout of an element not associated to a valid resource.

the latest version of R4E does not leave the properties view opened after closing a review group (Bug 359615)
