R help - Aug 2012 - ggplot2 geom_bar produces white slashes in legend keys

When I am using geom_bar I get these white slashes through the legend keys. I
cannot figure out how to remove them.
ggplot(diamonds, aes(clarity, fill=cut)) + geom_bar()

I have tried using opts(legend.key = theme_blank()) but with no luck.

Any suggestions would be much appreciated.

I am using R vers. 2.15.0 and ggplot 0.9.1, win xp

Best wishes
Jonas Hal

I cannot reproduce this unless you are referring to the white lines between each
level of the cut factor.  See http://www.mediafire.com/view/?14k2z7a1x3ln9nh for
my results.

Are we using the same ggplot2 version?  See sessionInfo below.
