Can't enter decryption password on CLI with Mac OS X

Although I'm able to use the CLI on Linux (Fedora 19) the CLI decryption does not allow me to enter a password on Mac OS X.

Scenario is:
- Run `keybase decrypt --signed`
- Paste in message, then enter CTRL-D. This works fine and I can see the encrypted message appear in the console after I paste it.
- Type in my password. No stars appear as I enter my password.
- Press enter. Nothing happens the first time I press enter.
- Press enter a second time. The prompt about requiring a password appears a second time.

Version information:
- Mac OS X 10.9.2

No source file or test is named. Start by reproducing `keybase decrypt --signed` on Mac OS X with the reported versions and compare its password-input behavior with Linux; done means the password prompt accepts input and decryption proceeds after the pasted message.
