I think that you are using too old AUCTeX.

This form of invocation of pdf2dsc turned out to be bogus and was fixed
a few years ago.

I recommend to upgrade AUCTeX. Using elpa would be convenient:

1. Delete the current installation of AUCTeX.
2. Restart emacs sesstion.
3. M-x package-install RET autex RET

If it doesn't work for you, please report back the detail.
