Hah, ouch!  =]

ISP mode is disabled while in debugWIRE (I suspect this is due to RESET pin being reallocated).

The way I have used to get out of dW is to use HVPP or HVSP mode (depending on the device).  That's what my shield does.  You can also use the Dragon for this, but I don't think it can be done with avrdude (unless there is a way avrdude can invoke HVPP/HVSP mode).  I have used AVR Studio for this in the past.

I do not have an arduino. Do you know something about the problem other than a device you want to sell ?

Shameless self-promotion: if you have an Arduino this shield will let you reset the fuses to get out of dW:
