Seems you're using the Stk500 - check the software oscilator frequency 
on the board. If it's too low or too high programming may fail. (You 
can set this through uisp builds dated after 14 Jul 2003, or AVR 
Studio) It seems to work best with the 1.2Mhz 'default' frequency. I 
had a similar problem myself a few weeks ago.

Also, triple-check the byzantine wiring needed to get the STK500 talking 
with the Tiny12. I've messed that up countless times. :)
