Sorry for not being really helpful,
but there have been substantial S4 related changes to R-devel since r39012 -- particularly about method dispatch.

Could you also try to use last night's r39045 (or something newer)?

There are several R developers who are really eager testing the new S4 code inside R-devel.
For those R-help readers not subscribed to R-devel and interested it this: Please look at
  https://stat.ethz.ch/pipermail/r-devel/2006-August/039088.html and consider reading the "accompanying" paper by John Chambers "How S4 Methods Work" .

Followups on this topic do rather belong to R-devel than R-help I think.
