Thanks for the report with simple MWE. I can confirm the behavior.
To developers:
(1) I think the attached patch circumvents this issue. However,
`TeX-parse-error' contains similar loose treatments for other
messages from (La)TeX. Should we add refinements to the rest of the
function as well?
(2) (This item isn't related to my patch; it has persisted with AUCTeX
for fairly long period.)
Looking at the regexp used in `TeX-parse-error', the parts "Hook
to change line numbers" and "Hook to change file name" are not
actually matched because preceding alternative parts "New file" and
"End of file" match instead. Thus the accompanying codes at later
part of the function never run, IIUC:
----------------------------------------------------------------------
;; Hook to change line numbers
((match-beginning 5)
(setq TeX-error-offset
(list (string-to-number (TeX-match-buffer 5))))
t)
;; Hook to change file name
((match-beginning 6)
[...]
----------------------------------------------------------------------
Is that OK? Or am I missing something?

Subject: [PATCH] Be more robust against false positive
* tex.el (TeX-TeX-sentinel-check,TeX-parse-error): Check whether
"file" really exists. If not, ignore it.
