asterisk users - Dec 2008 - 1.6.1-rc4: extension "i" not working??

I've have a simple caller id lookup on incoming:

[teliax-in]
..........
exten =>s,n,GoSub(set-callerid-name,0${CALLERID(num)},1)
................

[set-callerid-name]
exten => 0,1,NoOp( no CALLERID num set)
exten => 02135590993,1,Set(CALLERID(name)=Matthew )
...............................................
exten => _0!,n,NoOp(CALLERID: ${CALLERID(name)})
exten => _0!,n,Return()

exten => i,1,Return() ; somebody else

Now if there's a callerid that's listed, it all works OK. If there's
no
callerid, that works. But if there's an unknown callerid, I'd expect 
that to go to the invalid extension  - "i" - and Return().  But look 
what happens:


     -- Executing [2136398447 at teliax-in:4]
Gosub("IAX2/poseidon-15117",
"set-callerid-name,02136990505,1") in new stack
[Dec 25 13:06:32] ERROR[26483]: app_stack.c:286 gosub_exec: Attempt to 
reach a non-existent destination for gosub: (Context:set-callerid-name, 
Extension:02136990505, Priority:0)
   == Spawn extension (teliax-in, 2136398447, 5) exited non-zero on 
'IAX2/johnfbeatty-15117'
     -- Hungup 'IAX2/poseidon-15117'
     -- Hungup 'DAHDI/4-1'

Is this a bug in 1.6.1, or an improper use of the "i" extension?

Extension "i" does not work that way.  "i" is for invalid
selections
when using an IVR (well really when using the WaitExten application or 
when autofallthru is no or when using Background)
