Dear notmuch developers, I use notmuch-mode for GNU Emacs for managing my email. I think I have found a bug in notmuch-mode: If I do “.-v” on the line “[ 2015 _ Richtlinien.pdf: application/pdf ]”, then notmuch will open three windows of zathura (the PDF viewer I use). It seems to me that someone here either forgot quoting or decided to split filenames on spaces. I suggest that “2015 _ Richtlinien.pdf: application/pdf” should be quoted in notmuch-show-view-part. Note that saving attachment (“.-s”, notmuch-show-save-part) generally works even if the attachment file names have spaces. In case it matters, I normally use the rc(1) shell in Debian <http://tobold.org/article/rc>. Greetings, -- Nils Dagsson Moskopp // erlehmann <http://dieweltistgarnichtso.net>
