Well, that's better than no response at all. ;-)

That smells like running the ISP with a too high speed. As it is
technically an SPI, you must not clock it with more than F_CPU / 4.
The Dragon's default setting is 1 MHz (IIRC), so is way too high
for the default 1 MHz RC oscillator.

Try running it with -B 10 to make it slower.

Never trust an operating system you don't have sources for. ;-)
