8-) To let others chip in, let's try on data that are available to
8-) everyone:
8-) example(summary.manova) # includes defn. of Y, rate, additive
8-) fit <- manova(Y ~ rate + Error(additive))
8-) fit
8-) summary(fit)
8-) summary.aov(fit)
8-) summary(fit[[1]])
8-) summary(fit[[2]])
8-) summary(fit[[3]])
8-) of which only the raw print of "fit" and the very last line give
8-) sensible results. 

	With my own data, I do get output from summary(fit), and not the error message that arises in this case. And, indeed, summary(fit[[1]]) says "No error degrees of freedom". I can make this data available to everyone, but please indicate what the best way to export it is.

8-) Anyone have further clues?

Maybe the result class:

> example(summary.manova)
> class(fit)
[1] "manova" "maov"   "aov"    "mlm"    "lm"    

> fit<-manova(Y~rate + Error(additive))
> class(fit)
[1] "aovlist" "listof"
