@SYMTestCaseDesc    Tests that a zero length buffer does not cause an indefinate loop during verify 

@SYMTestPriority    Normal

@SYMTestStatus      Implemented

@SYMTestActions    	Creates a buffer, puts it into a TWsGraphicMsgBufParser and calls verify on it
					then removes the message from the buffer and re-tests verify.

@SYMTestExpectedResults Test should pass and not timeout
