Question: Problem with polarplot in Maple 15 (both 15.00 and 15.01)

There no curve on the second of the following two polar plots. Why? (I am using the 64 bit version on W7)

restart:

with(plots):

polarplot([3+4*cos(theta)],theta=0..2*Pi, radialstart=-2,angularorigin=bottom,legend=["Zero wind"], legendstyle=[location=top,font=[Times,roman,14]],labels=["G-force [G]",""], font=[Times,roman,14],labelfont=[Times,roman,14],tickmarks=[default,[Pi/4="",2*Pi/4="",3*Pi/4="",4*Pi/4="",5*Pi/4="",6*Pi/4="",7*Pi/4=""]]);

N:=200:

t:=[seq(evalf(2*Pi*(i-1)/(N-1)),i=1..N)]:

values:=[seq(evalf(3+4*cos(t[i])),i=1..N)]:

polarplot([[seq([values[i],t[i]],i=1..N)]], radialstart=-2,angularorigin=bottom, legend=["Zero wind"],legendstyle=[location=top, font=[Times,roman,14]],labels=["G-force [G]",""],font=[Times,roman,14],labelfont=[Times,roman,14], tickmarks=[default,[Pi/4="",2*Pi/4="",3*Pi/4="",4*Pi/4="",5*Pi/4="",6*Pi/4="",7*Pi/4=""]]);
