Single Process Deadlocks

$

Hi,

Below is the deadlock which occurs when running a SELECT statement. I was puzzled by this dead locks as there is only a single process (spid 79) involved in the deadlock. 
Somehow the SQL Server doesn't add any Deadlock graph event Profiler trace. The server is running SQL Server 2008 R2 with CU13.
