Gmail error: 'Unable to append message to folder' about larch HOT 3 OPEN

In my testing, Gmail accepts blank subject lines just fine. In any case, this message does appear to have a subject line (notice the 'Re:').

Gmail returns the "Unable to append message to folder" error when it can't parse the message for some reason, so it's likely there's something else wrong with this message that's causing the problem.

I don't suppose you'd be willing to share the raw message source with me, would you? I understand if you'd rather not.

yes, I have read about others having the same problem:

thanks rgrove. you are right, the subject does have 'Re:'

But there is something about certain subjects that causes a problem. I had the same issue when I used my mail client (Mail.app for OSX) to copy email messages. It always get hung up on blank subject lines (or those with just Re:).

I would be more than happy to share the raw message with you. I'd love to isolate the issue myself. I have your email address from your GitHub profile. I'll send it over.

Thanks.
