Yeah, and I can reproduce it only if I additionally use the xetex
TeX-engine.  Here's the backtrace:

Debugger entered--Lisp error: (quit)
  call-process("synctex" nil (#<buffer  *string-output*> nil) nil "view" "-i" 
"18:0:transformation-diss.tex" "-o" "transformation-diss.pdf")

TeX-source-correlate-output-page-function) "1"))()
  apply((lambda nil (if TeX-source-correlate-output-page-function (funcall
