Hi!

Doing a simple

(shell-command-to-string "/bin/ls")

I receive this

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  call-process(nil nil t nil "-c" "/bin/ls")
  shell-command-to-string("/bin/ls")
  eval((shell-command-to-string "/bin/ls"))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp nil nil)

Doing the same as root I get a correct result without error.

I do run:

GNU Emacs 23.4.1 (i486-pc-linux-gnu, GTK+ Version 2.24.10) of 2012-09-09 on murphy, modified by Debian

I cannot find the problem. I aƶready changed my login shell from zsh to sh but without success.

Can anybody help me please?

Cheers, Rainer
