R help - Oct 2009 - ggplot2: Histogram with negative values on x-axis doesn't work

I have a dataset that contains numbers between -10 and 0. E.g. x = 
c(-9.23, -9.56, -1.40, ...)
If I no do a
> qplot(x, geom="histogram")
I get the error:
Error: position_stack requires non-overlapping x intervals
Strangely, the following both work:
> qplot(x * -1, geom="histogram")
> qplot(x+100, geom="histogram")
Has anyone else encountered this? Is this a bug in ggplot2, or do I get 
anything completely wrong here?

I can reproduce it with for example
x=c(-9.23, -9.56, -1.40)

But adding a single positive number, even .0000001, fixes it, while 
adding a similar negative number introduces a new error message, so it 
really looks like a bug in ggplot2 when all the values are negative.

Report it to the ggplot2 author or the ggplot2 mailing list.
