Empty AsQueryable creates an Exception

Hello,
if i call a sql-Query with zero results (empty table) to deliver a Queryable:
it will throw a
for either
or
is this an expected behaviour?
I am using .NET4.0 EF, Devart.Data.Oracle.dll 6.70
I couldnt find mentioning it in the recent release notes, so it may probably still present in the latest Release.
