I can live with the use of break if you think it's superior, but I think
the idiom of "goto DONE" is more common in the notmuch codebase. I
personally always have think about the semantics of "break" and
"continue" in C pretty carefully.

It's not really clear to me what kind of "invalid" causes
g_mime_header_get_value to return NULL. Maybe this strcmp should be
guarded against that?
