Under R version 0.6.51  the following 

A_c(13,9,15,5,25,15,3,9,6,12)

kaeufe_c(A,B,C,D)
region_factor(rep(1:4,c(10,5,8,6)),labels=LETTERS[1:4])
anova(lm(kaeufe~region))   

delivers

This is what I expected. Under RW 1.0.0 I get

Analysis of Variance Table

Response: kaeufe
Error in print.coefmat(x, digits = digits, signif.stars = signif.stars,
: 
        binary operator applied to invalid types

Am I doing something wrong or is this a real bug?

It's not happening on Unix... Does this happen when starting from a
blank workspace?

The submitter told me in private email that the problem disappeared
when starting with a blank workspace, so a critical function probably
had been overridden.
