Exiv2

I am getting the following error on a particular photo.
"Iop entry 2796 lies outside of the IFD memory buffer"

this photo actually ->

Is there a way I can magically tell Exiv to just work anyway and not
 worry about the IFD thingo (this could be a very stupid statement as
 maybe the IFD is very core to the JPEG or something but I don't know
 much about JPEG - thats why i need the exiv library :) )?

I've googled for this error and there doesn't seem to be much mention
 of it so perhaps it is a one off wierd one.
