Still an issue for me, deleting the item from the Keychain didn't help. Note though that after I removed it from my keychain & tried submitting again, afterwards I got an e-mail in my Google account saying:

Going to https://www.google.com/settings/security/lesssecureapps brings you to a page that gives you a choice to revert your account back to "less secure", which I'm guessing Quicktime is one such app.
If so, kinda ridiculous that Apple hasn't updated the app.
