[Rd] Floating point excepting when cbind()ing a matrix of grobs (or environments) with a 0-column matrix

[hadley wickham]

library(grid)
e <- rectGrob()
# OR:
# e <- environment()

a <- matrix(list(e), ncol = 1, nrow = 2)
b <- matrix(ncol = 0, nrow = 2)

cbind(a, b)

cbind(a, b)

This reliably crashes R for me.

I realise this is a rather esoteric error condition, but it crops up
for me when creating matrices of grobs to be turned into a ggplot2
plot.
