[R] ggplot2 histograms

In my real data which has potentially 250 bins the problem becomes much more pronounced. Has any one else noticed this? Is there a work around?

What do you expect this to do?  The bars are one unit wide, but you've
told position_dodge to treat them like they're only 0.99 units wide.
