Display suite problem with Relation and EntityFieldQuery Views Backend modules

Hi,
I installed all of these modules and got several errors and when I checked the code the problem was that they are getting all the entites with entity_get_info() function and trying to get "base table" and ['entity keys']['id'] indexes from every element of the result and because Display suite Views entity does not have these indexses these modules throw errors.
I wrote to them too and I don't know who should fix this - maybe all of you :)
I just tried to help as much as I can (I'm a newbie yet :)
