It's nice to hear that this problem might be a bug, and
that it can be fixed with ylim. I've been using the
following function to get around it for barplots of
matrices. So, for example, if m1 is a matrix, I say
barplot(fill(m1))
fill <- function(x) {x[x=="NA"]<-0 ; return(x)}

I've put in a fix for 1.3.1. Not sure what the intentions were, but if it worked when ylim was set (for vertical barplots) it should work if it is unset.

Ouch! Use is.na(x) not x=="NA". The first is a proper test for NA or NaN. The second coerces to character and tests equality of strings. This is slower and not quite the same:
x <- c(0, 1, NA, 0/0) x
[1] 0 1 NA NaN
is.na(x)
[1] FALSE FALSE TRUE TRUE
x == "NA"
[1] FALSE FALSE TRUE FALSE
