There's a problem I noticed in the (?nearly-)latest cvs patches to v5.8.0.

The error occurs for me upon Gnus startup in the
`mail-source-set-common-1' function in `mail-source.el'.  Attached are
my patch and also the backtrace of the error.

Those of you who understand the guts of the `mail-source' processing
could probably determine if this is a true fix or simply a band-aid to
cover up a more fundamental problem ... but it at least got Gnus
running for me again.

Because I'm not sure if this is a real fix or just a band-aid, I'm not
attempting to apply this patch to cvs (and so far no having tried to
apply anything else to cvs, I'm not even sure if I'd be authorized to
do so).  Therefore, if someone who can apply cvs patches determines
that this indeed is a bona-fide fix, then it would still have to be
applied to the archive.

In case this matters, these are my `nnmail-*' and `mail-source-*' variables
from my `.gnus.el' file:

  (setq nnmail-spool-file
         '((directory :path "/home/me/Mail/instuff/"
		      :suffix ".in"))
      nnmail-use-long-file-names t
      nnmail-cache-accepted-message-ids t
      nnmail-crosspost nil
      mail-source-directory "~/Mail/Incoming/"
      mail-source-delete-incoming nil
      mail-source-movemail-program "/usr/bin/movemail"
  )


I hope this helps ...
