After upgrading to [Aquamacs based on] a pre-release of 24.4, a user complained about Tramp not working.
Some investigation showed that the error was reproducible with a
(load “tramp” nil)
and it occurred when it tried to load the file specified in `tramp-persistency-file-name’. The error message was:
eval-buffer: Invalid function: (["scpc" "dr” “xxx.yyy.org" nil] ("uname" "Darwin 9.8.0") ("test" "test") ("remote-path" ("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/usr/local/bin")) ("remote-shell" "/bin/sh") ("~" "/Users/dr") ("readlink" nil) ("perl-file-spec" t) ("perl-cwd-realpath" t) ("perl" "\\perl") …)
The file contents of the file specified in tramp-persistency-file-name began with
> ; Tramp connection history. Don't change this file.
> ;; You can delete it, forcing Tramp to reapply the checks.

This does not look like a file that can be loaded with `load’.
It was probably produced with an older Emacs version, but judging from the file date, probably just the previous release 23.3.
Deleting the file makes the error go away. Tramp works just fine then.
I think Emacs should be smart enough to handle the version upgrade. Perhaps re-generating the file if reading it produces an exception should be a transparent and automatic measure.

It's not about version incompatibility.
Tramp's persistency file is not something which shall be loaded by (load
“tramp” nil). Its default location is (locate-user-emacs-file "tramp")
If the directory is in the load-path, and if it is before the directory
where Tramp *.el[c] files reside, it might be that (load “tramp” nil)
takes the wrong file. Maybe, we shall move it either into a subdirectory
of "~/.emacs.d/", or we shall give it another name.
Hmm, I won't do it just now, because I'll be almost offline for the next
3 weeks (just email connection). I'll check it when I return; maybe
somebody has a better proposal.
Best regards, Michael.

We already added a startup warning if user-emacs-directory is in
load-path, for precisely this kind of reason. (Eg calc has similar issues.)
user-emacs-directory is not in load-path by default, so the question is;
how did it come to be in load-path, and why was the warning not seen?

And indeed there is exactly the issue with calc in the original report:

So you recommend to change nothing in Tramp, right? That's what I could
do best :-)

That’s because the warning is given only if the directory name is .emacs.d (string-match-p "/[._]emacs\\.d/?\\'" dir).
Had I seen this warning, I would have not have set the load-path default in Aquamacs to include user-emacs-directory.
At this time, it’s an inconvenient change for the user base… I’m not sure whether to leave it as is, or to change `user-emacs-directory', tweaking `locate-user-emacs-file’ to move files like “tramp.el” into a new subdirectory.

This is an Aquamacs-specific problem then.

The questionable configuration is, of course.
The lack of warning is not. I pointed out what the bug is in my other e-mail.

user-emacs-directory is a constant. You should not have changed it.

You’re right, it’s a constant. If you do have a constant for this, assuming that the file name is .emacs.d or similar in startup.el is obviously poor style.
I changed it because the home directory is not where applications should store files in the Mac OSX system.
Hiding the folder with a dot is helpful, because the directory does not show up in Finder. Yet, the correct place for such files would be in ~/Library/Preferences/Emacs/.
There is a special case for Windows, perhaps because the dot-filename syntax won’t work.
There are differences in philosophy between GNU Emacs and Aquamacs Emacs. This may be one of them.

And you get to fix the bugs that result from that! :)
But I applied this:

Why not simply remove the (string-match-p "/[._]emacs\\.d/?\\'" dir) test?
AFAICT the next string-equal test (which should/could probably be
replaced by a file-equal-p test) is already more strict than what
you added.

It may have been a pointless attempt to avoid statting the file-system
unless it looked like it was going to be needed. (Does expand-file-name
even do that?)

No, expand-file-name doesn't touch the file-system. And neither does
file-name-as-directory. These are just string operations.
Using file-equal-p would, OTOH.
