(wrong-type-argument arrayp nil) in IDNA code

(wrong-type-argument arrayp nil) in IDNA code

[Colin Marquardt]

Hi,

I got the gnus-CURRENT-20030506 CVS snapshot (after running Oort
0.12 succesfully) and now encounter a problem when wanting to send
mail. Here is the backtrace:


Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  substring(nil -1)
  (string= (substring string (1- ...)) "\n")
  (if (string= (substring string ...) "\n") (substring string 0 (1- ...)) string)
  (if (null proc) (error "Cannot start idn application") (idna-to-ascii-response-clear) (process-send-string proc (concat str "\n")) (setq string (idna-to-ascii-response)) (if (string= ... "\n") (substring string 0 ...) string))
  (let ((proc ...) string) (if (null proc) (error "Cannot start idn application") (idna-to-ascii-response-clear) (process-send-string proc ...) (setq string ...) (if ... ... string)))
  idna-to-ascii("alcatel.de")
  message-idna-to-ascii-rhs-1("From")
  message-idna-to-ascii-rhs()
  message-generate-headers((From Date (optional . In-Reply-To) Message-ID (optional . User-Agent) (optional . References) From))
  message-setup-1(((To . "") (Subject . "")) nil nil)
  message-setup(((To . "") (Subject . "")) nil nil)
  message-mail()
  gnus-group-mail(nil)
  call-interactively(gnus-group-mail)


I don't have any of the IDN support installed.

gnus-use-idna's value is t
message-use-idna's value is ask

I guess I can easily customize these variables to be nil, but things
should work out of the box. This is on a Solaris 5.8 machine in case
it matters. I don't think I have anything suspicious in my setup, but
I'm wondering why other people don't have this problem apparently?

Cheers,
  Colin

I think you have idna.el installed, at least, since gnus-use-idna is
nil if you don't.

They probably don't have idna.el installed, or have both idna.el and
the idn command line utility installed,

Thanks, this works.

Right, I dropped it into my goodies directory after you posted them
on g.e.s. but didn't install the command line utility.

Thanks again,
