[Bioc-devel] DataFrame errors with a Surv class column

Running and updated Bioc 3.5:

library(survival)
set.seed(1)
cens <- sample(0:1, 100, replace=TRUE)
time <- rnorm(100)
df = DataFrame(time=time, cens=cens, y=Surv(time, cens))
df[1:3, ]  #OK

DataFrame with 3 rows and 3 columns
        time      cens               y.from
   <numeric> <integer>               <Surv>
1  0.3981059         0  0.398105880367068:0
2 -0.6120264         0 -0.612026393250771:0
3  0.3411197         1  0.341119691424425:1

df #error

DataFrame with 100 rows and 3 columns
*Error in unclass(x)[i, , drop = FALSE] : subscript out of bounds*

This came up after I noticed something similar in
MultiAssayExperiment::wideFormat() when trying to reshape a Surv column,
but I'm not sure it's a bug in MultiAssayExperiment:

library(MultiAssayExperiment)
miniACC$y <- Surv(miniACC$days_to_death, miniACC$vital_status)
res = wideFormat(miniACC["EZH2", , ], colDataCols="y")

Show Traceback
