No apache logs since upgrade to slink

[Peter S Galbraith <GalbraithP@dfo-mpo.gc.ca>]

Apache no longer logs hits since I upgraded to slink.
I have not changed /etc/apache/httpd.conf and it contains the lines:

 LoadModule config_log_module /usr/lib/apache/1.3/mod_log_config.so
 ErrorLog /var/log/apache/error.log
 TransferLog /var/log/apache/access.log

Files are there, but empty:
 
 -rw-rw-r--   1 www-data www-data        0 Apr 18 06:42 access.log
 -rw-rw-r--   1 www-data www-data        0 Apr 11 06:42 access.log.0

Any ideas?
Thanks
