[Message part 1 (text/plain, inline)]

Okay, I think that one was my bad, as I was using the unmaintained melpa 
version.
But now I ran into another error in the same advice with the elpa 
version 1.7.2.

This is the error I'm getting now:

Debugger entered--Lisp error: (void-variable size)
  ad-Advice-abort-if-file-too-large(#f(compiled-function (size op-type 
filename &optional offer-raw) "If file SIZE larger than 
`large-file-warning-threshold', allow user to abort.\nOP-TYPE specifies 
the file operation being performed (for message\nto user).  If OFFER-RAW 
is true, give user the additional option\nto open the file literally.  
If the user chooses this option,\n`abort-if-file-too-large' returns the 
symbol `raw'. Otherwise,\nit returns nil or exits non-locally."

Not completely sure I understand you correctly, but this also happens 
when I directly load the file via
~(load "~/.emacs.d/elpa/vlf-1.7.2/vlf-setup.el")~ instead of ~(require 
'vlf-setup)~.
I don't see a "vlf-setup.elc" file in the "vlf-1.7.2" folder.
The error also happens when I start emacs with ~emacs -q~.
