Dear Tassilo,

edebug is something that I never used before. But I'm reading the docs 
and if I manage to get something out of it, I'll let you know.

This is what I can report so far:

- `M-x list-load-path-shadows RET' does not list any paths

- I've tried with Emacs 27.1 in its "virgin" state by making my .emacs 
completely empty and by just having nothing but the four lines to load 
AUCTeX in my site-start.el ... the error remains.  

Best,
Uwe
