ok, my theory about single-precision floats was probably wrong:
irb(main):009:0> 1.0/2**256
=> 8.63616855509444e-78

So as long as SOAP doesn't convert between different float 
representations, i have no idea where this error comes from.

Yes, and "unknown host" with "ping localhost", so i added localhost to my 
hosts file, which got rid of those errors... ;)

Ok, now only the four float errors are left:
