+mailbox: no such file or directory (errno = 2) when trying to attach files

[15bitgames]

I've been using NeoMutt for a while and recently I noticed that if I change mailboxes with a folder hook and then create a new email and want to add an attachment I get the following error.

+work: No such file or directory (errno = 2)

My mailbox is symlinked to another directory (/mnt/random/mail) so as a test I decided to move the mailbox to my home directory and it still didn't work (where the symlink originally was).

Below are links to my configuration files and I've also attached a debug file where you can see the issue at the end of the file. There is no sensitive information in the configuration files.

Is there some kind of mis-configuration somewhere? I couldn't find much online about the issue.

[somini]

Does your attachment path includes spaces? I get a similar error when I paste a path that includes spaces, and have to manually navigate to it.

[15bitgames]

I can't even manually navigate, and none of the directories have spaces in them.

[d-k-c]

I tried but cannot reproduce the issue you're facing. Can you try to reduce your config files to the bare minimum and detail the steps you do to trigger the issue?

[flatcap]

Is this still a problem? Did you try to minimise your config as @d-k-c suggested?

[BrunoMSantos]

I just stumbled on this issue. Interestingly enough I changed nothing in my configuration and I've been running later versions than the one that triggered this issue.

I can try to bisect the issue because it probably related to a recent update. But let me describe something that may be at the root of the issue:

The issue is not present when neomutt is fired up, it's only after using one of these macros (I have similar ones):

macro index ,g "<change-folder>+gmail/INBOX<return>" "change to gmail mail"

Replacing the + in those macros with a normal path fixes it. In fact the error message for that case would be:

+gmail: No such file or directory (errno = 2)

It seems to me that the + is not expanded in those macros. Does this help with reproducing the problem? Of course a long time has passed so it may not be directly related with the original issue.
