How do I fix Truffle deployment not working on struct array: “components found but type is not tuple; report on GitHub.”?

Question

I wrote the following, which compiles in truffle just fine, but will not deploy. I get the error "components found but type is not tuple; report on GitHub." Am I doing something wrong appending to a struct array?

pragma solidity ^0.5.0;

contract Sandbox {

  struct Leader {
    address host;
    uint fitness;
  }

  Leader[] public myList;

  function append(uint value) public {
    Leader memory leader = Leader(msg.sender, value);
    myList.push(leader);
  }

}
