facet reordering with new layer+data?

[baptiste auguie]

Dear list,

I am very puzzled by this odd behaviour,

library(ggplot2)
set.seed(123)

d <- data.frame(x=1:15, y=rnorm(15), f=factor(rep(letters[1:3],
each=5), levels=letters[1:3]))

## all fine, facets are a, b, c
( p <- ggplot(d, aes(x, y)) + facet_grid(f~.)+
geom_path() )

d2 <- data.frame(x=2, y=2, f="b",
stringsAsFactors=FALSE) # to be sure

## now the facets are in a different (wrong) order!
p + geom_blank(data=d2)

Is this a known bug? Have I got a broken github install?

Thanks,

baptiste
