windows qt v1.5.5.2 console/rpc directive
 validateaddress F1D7xQKugtYCDmKeZyNTqeGQxgutDcorXa
causes the program to fault

this is the first thing unomp mining pool software (i use unomp to solo mine multiple altcoins) does
when it connects

it seems if you feed validateaddress an invalid address it properly returns 'false'
but feed it a good address and the program fault happens
