The following script generates an errant line in backend_ps
from pylab import *
x=arange(10)
a=plot(x,x**2,'bo')
b=plot(x,90-x**2,'rs')
fl=figlegend((a,b),('curve 1','curve 2'),'lower center')
fl.draw_frame(False)
savefig('figlegend_bug')
but not in agg. It only happens when the legend frame is off.
This is sf bug
