[Pkg-mutt-maintainers] Bug#884858: mutt: q and $ fail with: rename: No such file or directory (errno = 2)

[Adam Borowski]

Package: mutt
Version: 1.7.2-1
Severity: normal

Hi!
Sometimes, quite rarely, operations that would commit operations on a
directory (such as q or $) fail with:
    rename: No such file or directory (errno = 2)
with no way to save changes.  This results in doubled mails that were moved
elsewhere, restoration of deleted mails and similar loss of status updates.

I use Maildir; there's also a dovecot running on the server with Thunderbird
connected to it over IMAP, although it hasn't been interacted with in any
way (I use it as a glorified biff, and sometimes to handle broken HTML mails
from a business critter).

Attached strace says:
write(1, "\r\33[59dWriting /home/kilobyte/Mai"..., 39) = 39
stat("/home/kilobyte/Maildir/new", {st_mode=S_IFDIR|0700, st_size=0, ...}) = 0
stat("/home/kilobyte/Maildir/cur", {st_mode=S_IFDIR|0700, st_size=41524, ...}) = 0
lstat("/home", {st_mode=S_IFDIR|0755, st_size=68, ...}) = 0
lstat("/home/kilobyte", {st_mode=S_IFDIR|0755, st_size=2568, ...}) = 0
lstat("/home/kilobyte/Maildir", {st_mode=S_IFDIR|0700, st_size=1914, ...}) = 0
write(1, "\r\33[37m\33[40mWriting /home/kilobyt"..., 69) = 69
rename("/home/kilobyte/Maildir/new/1513779272.2794_0.tartarus", "/home/kilobyte/Maildir/cur/1513779272.2794_0.tartarus:2,") = -1 ENOENT (No such file or directory)
write(1, "\rrename: No such file or directo"..., 46) = 46

As Maildir is designed to allow concurrent access, changes from other
processes (such as dovecot here, another instance of mutt, etc) are
expected.  Thus, it's not reasonable to make the user lose any unrelated
modifications to other mails.
