Mumi inserts spurious underscore in bug title |

Guix,
See <http://issues.guix.gnu.org/49114>, which Mumi currently
titles
‘guix_ lint’ should catch certificate validation exceptions
There's no underscore in the original subject. It's also rendered
correctly in the grey ‘mail view’ div:

Perhaps due to my use of Unicode quotes. There's nothing
suspicious in the HTML.
Kind regards,

Thank you for your analysis!

As part of #60410 I rebuilt the xapian database (deleted it and then ran
“mumi fetch”), so it’s not that.
[… time passes …]
I think I found the culprit in mumi/debbugs.scm:
(define qp-pattern "=\\?UTF-8\\?Q\\?([^?]+)\\?=")
…
(let ((subject (or (assoc-ref properties "Subject") "")))
(if (string-contains subject "=?UTF-8?Q?")
(or (false-if-exception
(utf8->string
(quoted-printable-decode
(regexp-substitute/global #f qp-pattern
subject 'pre 1 'post))))
subject)
subject))
I’m probably not using quoted-printable-decode correctly. My apologies
for assuming a bug in Guile Email. I changed this with commit
9d7eb3c5efe6427a1a89fb3e4c7165259edff4dd, using parse-email-headers.

True. I’ll be sure to rebuild the index on the next upgrade.

Thank you, and a Happy New Year to you too!
