Commented Unassigned: EF6 rc1 Index was outside the bounds of the array Exception [1603]

I am getting the error 'Index was outside the bounds of the array' exception occuring when trying to execute a fairly large expression.

I have tested the expression with entity framework 5 and it works as expected, however when upgrading to entityframework 6 rc 1 the exception is thrown.

I have attached a copy of the call stack when the exception is thrown, and the query i am trying to execute.
