When I invoke movemail --version manually, I get 
movemail (GNU Mailutils 1.1)

After a while I guessed to type c to make the debugger continue, which
seems to be what it did, and it hit the break-point again:

<buffer name="*Backtrace*">

  call-process("/usr/bin/movemail" nil #<buffer  *temp*<2>> nil "--version")
  rmail-probe("/usr/bin/movemail")

  rmail-autodetect()
  rmail-movemail-variant-p(mailutils)
  rmail-insert-inbox-text(("/var/mail/eddy") t)
  rmail-get-new-mail()
  rmail()
  call-interactively(rmail)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)
</buffer>

and then c again:

<buffer name="*Backtrace*">

* call-process("/usr/lib/emacs/22.1/i486-linux-gnu/movemail" nil #<buffer  *temp*> nil "--emacs" "/var/mail/eddy" "/disk/home/eddy/.newmail-eddy")
  apply(call-process ("/usr/lib/emacs/22.1/i486-linux-gnu/movemail" nil #<buffer  *temp*> nil "--emacs" "/var/mail/eddy" "/disk/home/eddy/.newmail-eddy"))
  rmail-insert-inbox-text(("/var/mail/eddy") t)
  rmail-get-new-mail()
  rmail()
  call-interactively(rmail)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)
</buffer>

and again:

<buffer name="*Backtrace*">

  call-process("/usr/lib/emacs/22.1/i486-linux-gnu/movemail" nil #<buffer  *temp*> nil "--emacs" "/var/mail/eddy" "/disk/home/eddy/.newmail-eddy")

  rmail-get-new-mail()
  rmail()
  call-interactively(rmail)

  call-interactively(execute-extended-command)
</buffer>

after which I got the error,
