I'm suspecting that you have some big files in there, (such as indexes
from some other mail program). We had code in notmuch to detect and
ignore these, but a recent bug had broken that.

I just fixed this code as of the below commit. So please update and try
again and let us know if things work any better.

Thanks for your patience!

    add_message: Re-fix handling of non-mail files.
    
    More fallout from _get_header now returning "" for missing headers.
    
    The bug here is that we would no longer detect that a file is not an
    email message and give up on it like we should.
    
    And this time, I actually audited all callers to
    notmuch_message_get_header, so hopefully we're done fixing this
    bug over and over.
