I grabbed your  script from flashingtwelve.brickfilms URL above, set a 
path with Path tool and when I ran it (GIMP 2.6.6 - Windows XP SP3) got 
this in the error console:

      GIMP Error
    Calling error for procedure 'gimp-image-crop':
    Procedure 'gimp-image-crop' has been called with value '-160' for
    argument 'offx' (#4, type GimpInt32). This value is out of range.

      GIMP Warning
    Plug-In 'Rotate To Path Point' left image undo in inconsistent
    state, closing open undo groups.

      GIMP Error
    Execution error for 'Rotate To Path Point':
    Error: Procedure execution of gimp-image-crop failed on invalid
    input arguments: Procedure 'gimp-image-crop' has been called with
    value '-160' for argument 'offx' (#4, type GimpInt32). This value is
    out of range.

I notice that at the bottom of the original conversation the OP 
(StefanP) has a recent  unanswered problem (Sun Apr 26, 2009 2:18 am) 
after updating to GIMP 2.6 (not exactly the same error as  I got):

    It is me again. After upgrading to Ubuntu 9.04 and Gimp 2.6 I am now
    getting the following error after setting the path and executing the
    script:

    Execution error for 'Rotate To Path Point':
    Error: Bad syntax of binding spec in let* : ((vectors) (stroke-id)
    (points) (x1) (y1) (x2) (y2) (center-x) (center-y) (radius) (angle)
    (foo (car (gimp-image-get-filename image))))
