>Description:
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.

>How-To-Repeat:
- Install samba-3.0.4_3,1 with winbind
- Install apache-2.0.50
- 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:
