GetView returns IVIEW with IVIEWROWS which are NULL

We use couchbase views to retrieve some keys which worked fine in 1.2.9. However we upgraded to 1.3.6 in which we found view errors (See NCBC-507). Hence we reverted back to 1.3.5 and 1.3.4 which contained the following view error:

Code:
var itemtoremove = CouchbaseWrapper.Client.GetView("search", "customerid_productid").Key(new object[]

);

Returns an IView of IViewRows over which we enumerate. However some rows have the value null (not the properties of IViewRow but the reference to IViewRow itself is null). Which results in object reference not set exception when trying to handle the IViewRows. Which we ofcourse don't expect when processing the results of a view.
Currently I reverted back to 1.2.9 in which our code executes without any problems.
