SmartRefStream broken?

Ahoy!
We were having a discussion on #squeak about SqueakMap, older images,
and SmartRefStream. Eventually, we were sharing snippets of code. We
were trying to do the following:
"Save the data"
| data rr |
data := Dictionary new.
data at: #Meef put: 25;
at: 23 put: 'Amanda';
at: 'Small Numbers' put: #(0 1 2 3 four).
rr := SmartRefStream fileNamed: 'data.obj'.
rr nextPut: data; close.
"Restore it!"
| restoredData rr |
rr := SmartRefStream fileNamed: 'data.obj'.
restoredData := rr next.
restoredData inspect.
rr close.
This doesn't work. You can save the serialized object, but when you
try to run the restore snippit, you get a walkback. One note- it does
work just fine when you replace SmartRefStream with ReferenceStream -
that works fine on both the saving and the restoring. All examples
of serializing objects I can find involve ReferenceStream or an
ImageSegment, nothing with the SRS. That said, SmartRefStream has
some features that are useful and we'd like to use.
I won't put the whole walk back here- the code will bring up this
error in any image. I tried the following images-
2.2: doesn't exist there.
2.4, 2.8, 3.2, 3.4, 3.8: the same error.
My first question- are we using it wrong? Any other ideas?
Regards,
Aaron
