symbol rendering problem

[Kyle Wilcox]

My symbol is defined as follows:

Symbol
  Name 'arrow2'
  Type VECTOR
  Filled TRUE
  Points
    1 3
    1 -3
    4 -3
    0 -8
    -4 -3
    -1 -3
    -1 3
    1 3
  END
END

When I rotate the symbol as follows, only the right half of the image is
shown.  This only happens when ANGLE is '0'.  Because the actual values
for ANGLE are being pulled from a database, I can't change a '0'
appearing there often (when the wind is blowing true north).

CLASS
                NAME "< 12.5 m/s"
                KEYIMAGE "images/legend/70.png"
                EXPRESSION ([wind_speed] <= 12.5)
                STYLE
                        SYMBOL "arrow2"
                        ANGLE 0
                        COLOR 255 52 0
                        OUTLINECOLOR 0 0 0
                        SIZE 3
                END
 END


Here is a link to a map that is showing the problem:
