CUPS receiving blank username

I've been plagued by this issue for a few days now - it seemingly appeared out of nowhere because no changes were made to the software on my system or any of the configuration files.

When trying to print either locally or from a remote machine I'm seeing the following lines in my error_log:

D [13/Sep/2008:11:40:03 -0400] cupsdAcceptClient: 14 from localhost (Domain)
D [13/Sep/2008:11:40:03 -0400] cupsdReadClient: 14 POST / HTTP/1.1
D [13/Sep/2008:11:40:03 -0400] cupsdAuthorize: No authentication data provided.
D [13/Sep/2008:11:40:03 -0400] cupsdIsAuthorized: username=""
D [13/Sep/2008:11:40:03 -0400] cupsdSendError: 14 code=401 (Unauthorized)
D [13/Sep/2008:11:40:03 -0400] cupsdSendHeader: WWW-Authenticate: Basic realm="CUPS"
D [13/Sep/2008:11:40:03 -0400] cupsdCloseClient: 14

I know the remote machine is configured to send the username and password, and I'm not sure how the local jobs have worked in the past.  (I'm running Ubuntu 8.04).

My configuration file has the following relevant lines:
SSLPort 631
Listen /var/run/cups/cups.sock
