Can't figure that out; gdb complains that apache2 isn't edible:

`gdb /usr/sbin/apache2 core` gives:
This GDB was configured as "x86_64-linux-gnu"...BFD: /usr/sbin/apache2: don't know how to handle OS specific section `.gnu.hash' [0x6ffffff6] "/usr/sbin/apache2": not in executable format: File format not recognized

Core was generated by `/usr/sbin/apache2'. Program terminated with signal 11, Segmentation fault. #0 0x00002af1b553f5e0 in ?? ()
(gdb)

I haven't got knowhow with gdb, and rudimentary attempts at fixing didn't succeed. Please provide pointers on how to provide a backtrace.

To clear up, these are my installed packages: `aptitude search apache2 | grep ^i`:

i   apache2                         - Next generation, scalable, extendable web 
i A apache2-mpm-worker              - High speed threaded model for Apache HTTPD
i   apache2-src                     - Apache source code                        
i A apache2-utils                   - utility programs for webservers           
i A apache2.2-common                - Next generation, scalable, extendable web 
i   libapache2-mod-auth-pgsql       - Module for Apache2 which provides pgsql au
i   libapache2-svn                  - Subversion server modules for Apache

As for relevant config snippets, these are the result, when I merge them together:
