Comment(by ryan):

 funny...I can't reproduce this error on my local sage install.  However,
 on a remote sage install (i.e., sage.math), I get the error.  However, the
 error is triggered (I think) because the remote installation can't display
 graphics.

 Try:
 [[[
 a = point([])
 type(a)
 ]]]
 a is of type sage.plot.plot.Graphics()
