Issue with "view" access control

[Yves Martin]

 Hello,

I have troubles with my GNATS databases since I have upgraded from gnats
4.0 to gnats 4.1 (Debian Etch system) using gnatsweb as front-end

Since upgrade, a user with "view" access right always receive:
  server_reply: 220 No PRs match.
Whereas a user with "edit" or "viewconf" access right gets 52
non-confidential issues.

I have re-generated index for this database but without any positive
change.

What should I do to get it work again properly ?
Thank you in advance for your help
