In the development branch, the median lines don't appear in geom_boxplot when the following are both true:

* the y range is large
* coord_flip() is used

This works:

```
dat <- data.frame(x=sample(LETTERS[1:4],40,replace=TRUE), y=rnorm(40))
ggplot(dat, aes(x=x, y=y, fill=x)) +
geom_boxplot() + coord_flip()
```

But if the y values are scaled up by 100, the medians don't appear:

```
dat$y <- dat$y * 100
ggplot(dat, aes(x=x, y=y, fill=x)) +
geom_boxplot() + coord_flip()
```
