SwfObject Error

programming flash

I get this error when I publish my SWF using SwfObject

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at util::SWFAddress$/getPath()
    at util::SWFAddressEvent()
    at util::SWFAddress$/_dispatchEvent()
    at util::SWFAddress$/setValue()
    at index_v1_fla::MainTimeline/frame1()

It doesn’t effect how anything is working. Everything seems to be working fine. But I hate having an error message.

The only real line of code here is this:

SWFAddress.addEventListener(SWFAddressEvent.CHANGE, navigateToSection)
