Getting bogus "No OpenPGP message was found" message

[matthewadams]

First try at sending message using Chrome plugin. Sent ok, recipient replied. When I got reply, entered my private key password and hit the Decrypt button & got message "No OpenPGP message was found" (I cropped out the sender info in the screenshot below), which seems bogus. I hope it's not a stupid user error.

FYI, I copied the message, then piped it to gpg (I'm on Mac OS X El Capitan) and I successfully decrypted it. Notice the message gpg: invalid armor header: hQIMA3j021lyajDIARAApHs07IEzlS5CkcRw8mlheAY9Cn+vwS2rpTKMYysll1O5\n:

Here's output from gpg --version:
