It's an incompatibility with the latest version (2.3.1) of bip39 lib.
You can get around it by explicitly adding version 2.3.0 of bip39 lib to your package.json before ethereumjs-testrpc e.g.

"devDependencies": {
    "bip39": "2.3.0",
    "ethereumjs-testrpc": "^2.2.4",

@capamaster I'm so sorry this went for so long without a response! I think this is no longer an issue in the latest TestRPC (v6.0.2). If I'm mistaken, please reopen.
