This looks like you have some invalid entry in load-history, i.e., an
alist entry where the key is not a string but (require . info).  AUCTeX
doesn't mess with load-history, so the question is how that entry ends
up there.

It seems to happen when desktop-mode is loaded, so I suggest to disable
that for a moment to see if the error persist.

Do you have an explicit (eval-after-load "desktop" ...) in your .emacs?
And given the's advice-eval-interactive-spec in the backtrace, do you
have a piece of advice on TeX-latex-mode (it should be listed with C-h f
TeX-latex-mode RET).

Bye,
