Apache segfault on stop, restart or graceful when using winbindd on nsswitch.conf

           Summary: Apache segfault on stop, restart or graceful when using
                    winbindd on nsswitch.conf
           Product: Apache httpd-2.0
           Version: 2.0.50
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: All
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: renato@galle.com.br


I´ve installed samba-3.0.4_3,1 with winbindd and apache-2.0.50, samba is working
fine, but after I changed /etc/nsswitch.conf to add winbindd, apache starts to
generate a segfault on apachectl stop, restart and graceful.

Environment:

FreeBSD-5.2.1-RELEASE-p8

How-To-Repeat

- Install samba-3.0.4_3,1 with winbind via ports
- Install apache-2.0.50 via ports
- Add the following lines to /etc/nsswitch.conf:
passwd: files winbind
group:  files winbind
- Configure your smb.conf to work with winbind
- Start samba
- Start apache
- run apachectl restart

Here is the backtrace of the error:
