Customizing gnus-parameters refuses to work today

[Francis Moreau]

Hello,

Again Gnus puzzled me today.

I setup 'gnus-parameters' a couple days ago using the following
values:

(setq gnus-parameters
      '(("mail\\.inbox"
         (gcc-self . t)
         (display . default))

        ("save\\..*"
         (display . all))

        ("list\\..*"
         (total-expire . t)
         (gcc-self . t)
         (broken-reply-to . t))))

and AFAICT it has worked, I'm sure.

But today it doesn't anymore. Still I checked the value of
gnus-parameters and it looks fine. But doing 'G p' on a peculiar
customized group show me 'nil'.

Could anybody shed me some light ?

thanks

Francis
