[BUG][FIX]Browser explain of pooldicts fails ( [er][et] kills the class comment versions browser. Try this one.. )

[Ned Konz]

Open a browser, view the class comment ('?'), hit the versions button.
Before this CS you see the versions of the class comment, after you
don't.

Try the attached version. I still am not sure that this won't blow up
somewhere.
