Can't parse simple .proto composite message

[kybu]

This simple .proto file does not parse:

message Error {
    optional int32 code = 1;
    optional bytes message = 2;
    optional bytes data = 3;
}


message Request {
    optional Error error = 1;
    optional int32 whatever = 2;
}

It fails with a following error:

Sry, it took me a while to get it tested. It works now, thanks.
