broken woody

[debian@4th-world.com]

Hello,

after an "apt-get dist-upgrade" my system (woody) seems quite broken.
Apache and lprng among other daemons/progs are no longer working:

 #/etc/init.d/apache start
  Starting web server: apache.
  /usr/sbin/apachectl: line 171:  1603 Aborted                 $HTTPD
  /usr/sbin/apachectl start: httpd could not be started

 #tail -f /var/log/apache/error.log
  apache: options.c:326: ldap_set_option: Assertion 
  `( ( ld )->ld_options.ldo_valid == 0x2 )' failed.

Also my system load average is shown (with top) as being around 1.2 
although I can't see any obvious "culprit"-processes, and the system
doesn't "feel" loaded.

Also, I'm not certain that I am not at fault, because I have been
toying around with nsswitch and pam_ldap.so.

Any ideas/help??? -- Please!!! -- A newbie at loss.

Thanks,
Robert
