[Rd] strange error with rw2010dev

With rw2010dev I get a strange protect(): protection stack overflow error with a small data frame which otherwise is usable:

If anybody wants to have a look I can provide an RData file with the problematic data frame.

Doesn't seem to be necessary, the following simulated example generates the error:

> testmat <- matrix(1:80, 20,4)
> dim(testmat)

[1] 20 4
> str(testmat)

 int [1:20, 1:4] 1 2 3 4 5 6 7 8 9 10 ...
> testframe <- data.frame(testmat=I(testmat),

    x=rnorm(20), y=rnorm(20), z=sample(1:20))
> str(testframe)

`data.frame': 20 obs. of 4 variables:
 $ testmat: int [1:20, 1:4] 1 2 3 4 5 6 7 8 9 10 ...   ..- attr(*, "class")= chr "AsIs"

 $ x      : num   0.768 -0.462  0.450  0.476 -1.077 ...
 $ y      : num   0.453  1.227 -1.514 -0.904 -0.129 ...
 $ z      : int  10 4 15 19 14 3 9 17 18 5 ...

> summary(testframe)

Error: protect(): protection stack overflow
