In this example the errorbars do not align with the theta of bar. I posted this as a question at stackoverflow, and maybe the answer could be useful. Surely, this should not be default behavior though.
from numpy import *
from matplotlib import pyplot as py
r=zeros([16])
err=zeros([16])
for i in range(16):
r[i]=random.randint(400,600)
err[i]=random.randint(20,50)
theta=arange(0,2*pi,2*pi/16)
width = pi*2/16
fig = py.figure(figsize=(8,8))
ax = fig.add_axes([0.1, 0.1, 0.75, 0.79], polar=True)
bars = ax.bar(theta+pi/16, r, width=width, bottom=0.0,yerr=err)
ax.set_ylim(0,700)
py.show()
