I loaded a regular tex file and figured out that different latex packges 
have there own style file in auctex
subdirectory

looking in the file
auctex/style/subfigure.el i found the following setq command that fails 
when I try to execute it with the same error as i got before.

   ;; Install completion for labels:
   (setq TeX-complete-list
         (append
          '(("\\\\[Ss]ubref{\\([^{}\n\r\\%,]*\\)" 1 LaTeX-label-list "}")))
          TeX-complete-list)

maybe this is what causes the error. I don't understand why the error 
only happens for me though.
