nnir setup help: wrong type argument: arrayp, nil

nnir setup help: wrong type argument: arrayp, nil

[Pranav K. Tiwari]

I am trying to set up nnir for indexing nnml folders, and am having some
trouble. When I try to search for something, the search succeeds, but then
it fails while showing the results with the following traceback given
below.

nnir-version's value is 
"$Id: nnir.el,v 1.1.1.1 2003/04/04 20:16:09 lolando Exp $"

My nnir configuration is also included below.

Can anyone tell me what's broken?

thx,
-p

Hi Pranav,

    > That helped - filename displayed there gave a good clue. Works
    > fine now.

Great! Please would you describe what the error was - maybe it could
help other people having the same problems (and googling) and maybe i
can improve the documentation strings.

    > Thanks! -p

You're welcome!

Herzliche Grüße,
  Christoph
