bug when combining geom_hline() and coord_trans()

[ThierryO]

the first two plots work, the last one does not.

dataset <- data.frame(A = runif(100, 1, 10), B = rnorm(100))
ggplot(dataset, aes(x = A, y = B)) + geom_point() + coord_trans(x = "log10")
ggplot(dataset, aes(x = A, y = B)) + geom_point() + geom_hline(yintercept = 1)
ggplot(dataset, aes(x = A, y = B)) + geom_point() + coord_trans(x = "log10") + geom_hline(yintercept = 1)
