This was a minor oversite in checking of part type when outputing content raw. This was causing gmime was to throw an exception to stderr. Unfortunately the gmime exception was not being caught by notmuch, or the test suite. I'm not sure if notmuch should have done anything in this case, but certainly the test suite should be capable of detecting that something unexpected was output to stderr. --- This is a cleaner version of this patch. notmuch-show.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/notmuch-show.c b/notmuch-show.c index 9267d02..59f7078 100644 --- a/notmuch-show.c +++ b/notmuch-show.c @@ -644,6 +644,9 @@ format_part_end_json (GMimeObject *part) static void format_part_content_raw (GMimeObject *part) { + if (!
