Export Execution Results - REST does not work for Sub Test Execution (using filter)

Steps to Reproduce

1 - Create a saved filter with Sub Test Execution. Example: 

project = Calculator AND issuetype = "Sub Test Execution" AND status = Closed

2 - Use the endpoint

curl -u user:password http://yourserver/rest/raven/1.0/testruns?savedFilterId=1376

Result

Message: The search did not return any execution results or you do not have permissions to view them.

Expected result

Output with the information related to Test Runs. 

Update: This does not work also with REST API 2.0. The response is empty.
