Hi!

While testing your amazing tool it occasionally crashes while syncing my Gmail account with the following stack trace. Hope this is helpful.

Thanks again for providing this tool!

I've added a check for incomplete responses, in which case the email is skipped temporarily. In theory, future runs will get a complete response and manage to back up the email.
