httpd vs. avahi and SELinux in Fedora 11

[Steven F. LeBrun]

After doing a clean install of Fedora 11, the Apache webserver, httpd 
2.2.11, is failing.  The error log [see below] shows that all the httpd 
children are killing themselves with Segmentation faults.

Httpd was working fine in Fedora 10, same laptop and I started with a 
fresh install of Apache's httpd using the RPM provided for Fedora 11.  
At first I thought that maybe it is an SELinux problem.  Then I noticed 
in the error_log the following line:

     [error] avahi_entry_group_add_service_strlst("tardis") failed: 
Local name collision

The FQHN of my laptop where I am trying to run httpd is 
tardis.home.lebruns.com

Question 1:  Is the segmentation faults due to an SELinux policy issue?  
I checked the files that should be displayed and their security context 
looks correct.  Is there a problem displayed in the first error log line 
where it states:

   SELinux policy enabled; httpd running as context 
unconfined_u:system_r:httpd_t:s0

Question 2:  Any ideas of what is causing the avahi error message?  What 
causes a "Local name collision"?  None of the configuration files 
specify the host name that httpd is running on.  [Setting ServiceName 
did not change anything.]

The exit signal Segmentation fault (11) repeats ad nausium until httpd 
is stopped.

Any help and/or suggestions will be appreciated.
