Comment (by liuar):

 There will be a CURVEPOLYGON created when draging or clicking if the user
 chooses SelectRadius.[[BR]]
 [[BR]]
 For draging, a valid CURVEPOLYGON will be create by the center and
 radius.[[BR]]
 But for clicking, the radius will be 0 and the created CURVEPOLYGON will
 like:
 [[BR]]
 {{{
 CURVEPOLYGON ((7.629521563329069 19.93939991157145 (CIRCULARARCSEGMENT
 (9.193306642292184 18.375614832608335, 10.757091721255298
 19.93939991157145), CIRCULARARCSEGMENT (9.193306642292184
 21.503184990534564, 7.629521563329069 19.93939991157145))))
 }}}
 [[BR]]
 which is not a valid CURVEPOLYGON. That's why there's an exception thrown
 up. IE has the same problem but the exception is not displayed to
 user.[[BR]]
 [[BR]]
 To resolve this problem, we can try to validate the value of the radius
 before creating the CURVEPOLYGON. If the value equals to 0, just return.
