Hello list, I have a little problem here. I have a message of which I had multiple copies and I deleted one of them but "notmuch new" does not suppress this copy. $ notmuch search --output=files id:20150216180408.HA14616@myhost /home/francois/Maildir/my_first_box/cur/1424110151_0.24869.myhost,U=742:2,S /home/francois/Maildir/my_second_box/cur/1424110163_0.24869.myhost,U=14486:2,S /home/francois/Maildir/my_third_box//cur/1429004021.3224_3.myhost:2,S The last copy is the one I deleted. I tried to readd the message to this box and after I have this status : $ cp ~/Maildir/my_second_box/cur/1424110163_0.24869.myhost,U=14486:2,S ~/Maildir/my_third_box/cur $ notmuch new Processed 1 file in almost no time. No new mail. $ notmuch search --output=files id:20150216180408.HA14616@myhost /home/francois/Maildir/my_first_box/cur/1424110151_0.24869.myhost,U=742:2,S /home/francois/Maildir/my_second_box/cur/1424110163_0.24869.myhost,U=14486:2,S /home/francois/Maildir/my_third_box/cur/1429004021.3224_3.myhost:2,S /home/francois/Maildir/my_third_box//cur/1429004021.3224_3.myhost:2,S And if I redelete it I come back to beginning : $ rm ~/Maildir/my_third_box/cur/1429004021.3224_3.myhost:2,S $ notmuch new No new mail. Detected 1 file rename. $ notmuch search --output=files id:20150216180408.HA14616@myhost /home/francois/Maildir/my_first_box/cur/1424110151_0.24869.myhost,U=742:2,S /home/francois/Maildir/my_second_box/cur/1424110163_0.24869.myhost,U=14486:2,S /home/francois/Maildir/my_third_box//cur/1429004021.3224_3.myhost:2,S I don't know how the file path with double slash was added in the first place to the DB but I have a real problem with it. Anyone have any idea of how I can solve this ? $ notmuch --version notmuch 0.18.2 $ lsb_release -a No LSB modules are available.
