[Bioc-devel] rbind'ing for SummarizedExperiment with no rows

Dear List, Martin;

It looks like rbind'ing fails when the first argument is a
SummarizedExperiment with no rows:

library(SummarizedExperiment)
example(SummarizedExperiment, echo=FALSE)
rbind(se, se[0,]) # works okay; returns 'se'.
rbind(se[0,], se) # fails
# Error in rep.int(width, k) : invalid 'times' value

It might be a fairly silly example, but I would have expected it to just
give back 'se'.

Cheers,

Aaron
