I tried commenting out this part, but it still fails at another part im
amsmath.el:
(and LaTeX-reftex-ref-style-auto-activate
(fboundp 'reftex-ref-style-activate)
(reftex-ref-style-activate "AMSmath"))

The fundamental origin of the problem is that RefTeX presumes that it
always works in the buffer associated with files. In other words, RefTeX
pays no attention to non-file buffer. (I have such impression, skimming
over the RefTeX code. Please correct me if I'm wrong.)

I have basically the same idea, but I think such partial treatment
inctroduces inconsistent internal state of RefTeX and can be potential
problems. Rather I propose to wrap the whole RefTeX management
part in amsmath.el by (when buffer-file-name ... ). In addition, we
should turn off RefTeX mode in `TeX-mode-cleanup' like
(unless buffer-file-truename
(if (bound-and-true-p reftex-mode) <-- addition
(reftex-mode -1)) <-- addition
(TeX-update-style))
to avoid inconsistency.
