I downloaded debian-9.5.0-amd64-xfce-CD-1.iso several months ago via:

https://cdimage.debian.org/debian-cd/current/amd64/jigdo-cd/


<snip> - image sounds ok.

It fails with a pop-up dialog:

     	[!] Select and install software

	An installation step failed.  You can try to run the failing item again
from the menu, or

Note that I did not select a mirror.

Apparently, debian-9.5.0-amd64-xfce-CD-1.iso is missing the packages
required for a default installation (?).

If I go back and use a network mirror (my local Approx server), I can
finish the install successfully:

Can anyone confirm this bug?


Yes. I've just tested it and I can see the same problem. By switching
to the syslog (VT4) I can see that there problem is with the mutt
package:

There is a bug here, and I think it's possibly in tasksel. Mutt is not
on the installation CD, and neither are its dependencies libgpgme11
and libnotmuch4.

*However*, the installer has automatically added security.debian.org
to the sources.list of the new system and peformed an "apt-get
update". This found a security update for mutt, and mutt is Priority:
standard so tasksel decided it should be installed. But the
dependencies are not on security.debian.org and not on the CD -->
problem.

That's how this becomes a problem. For now, if you have security
updates installed then you'll need to enable a mirror or start with a
larger installation CD. Sorry... :-/
Thank you for confirming the defect, and thank you for the detailed analysis.
My intent was to install just what was on the CD onto a machine in my LAN. I was unaware that d-i connected to the Internet when I told it not to use a mirror. As security.debian.org is not a mirror in the usual sense, perhaps this kinda sorta makes sense to the Debian developers. For me, it violates KISS and the Principle of Least Surprise. I think the d-i needs to be more clear about if/ when it intends to connect to the Internet, and obtain explicit user approval. Which package do I file a bug report against?
I view the fact that the d-i couldn't obtain a security update package to be a defect in the Debian security package distribution chain. If 'apt-get update' finds that a security update package is available and the d-i wants to install that package, then 'apt-get update' must be able to download that package. Which package do I file a bug report against?
