Yup, I was finally able to reproduce the issue. I'm using msmtp to send
mail and have a `passwordeval` script that I use to yield the password.
Recently I've switched to a different password manager though, so I had
to adapt the script a bit. Basically, what the script does is to check
whether I'm already signed in -- if not, it spawns rofi to ask me for my
password.
But: rofi actually reads from stdin, and the `passwordeval` command in
msmtp explicitly must _not_ munge stdin, as stdin is where the mail gets
read from. So this is what caused the mail to get truncated.
So why wasn't I able to reproduce the issue? Well, because it only
happens in case the password store in locked and I need to input my
password. But when reproducing it I already had the password store
unlocked.
The fix is thus quite easy:
diff --git a/home-manager/profiles/graphical/workstation/gitlab/default.nix b/home-manager/profiles/graphical/workstation/gitlab/default.nix
index d47e95a83..3460a29fb 100644

Finally, another mystery solved. This really has been stressing me out
over the last two weeks.
