What steps will reproduce the problem?
Run the following:

drop dataverse test if exists;
create dataverse test;
use dataverse test;

create type TwitterUserType as closed {
screen-name: string,
lang: string,
friends_count: int32,
statuses_count: int32,
name: string,
followers_count: int32
} 

create type TweetMessageType as closed {
tweetid: string,
    user: TwitterUserType,
    sender-location: point,
send-time: datetime,
    referred-topics: {{ string }},
message-text: string
}

create dataset Tweets(TweetMessageType) primary key tweetid;
create index rtree_index on Tweets2(sender-location) type rtree;

for $x in dataset Tweets2
where spatial-intersect($x.sender-location, $x.sender-location)
return $x

You will get the following exception:
