No, they are not.

If you put them side by side, you'll notice that the Ruby program is 
sending an invalid message. The a{sv} argument of the call is being 
marshalled by Python as '\0\0\0\0' (empty), while Ruby is 
sending '\4\0\0\0\0\0\0\0' (4 bytes of data). 

And 4 bytes cannot contain one {sv}: the minimum acceptable would be the 
string's length (4 bytes), the terninating NUL for the string, one byte 
to encode the length for the variant's signature, the signature's one 
byte followed by a NUL and a single element of type BYTE.

So the Ruby message was invalid.
