yes.

at least not directly -- I'll examine all loaded third party modes as
soon as I can.

I observed an other problem, that seems to be related:
- I start Emacs using my .emacs
- M-x c-mode
- klick on the Menubar
=> I get: 
  Debugger entered--Lisp error: (void-variable c-subword-mode)

Of cause: w/o my .emacs the problem is not there, so something seems
to mess with cc-mode...

Now, when I:
- start Emacs using my .emacs
- M-x load-library cc-subword
- C-x 5 f /PATH/TO/ANY/FILE.c

It works without SEGV, so those problems seem to be related.
