Hi there, I'm also experiencing this problem when my print clients were upgraded from Ubuntu 10.04 to 12.04 [1]. The CUPS server [2] runs Debian Squeeze.
My main concern is DoS via file system space exhaustion, both error_log [3] and access_log [4] grow at very high speed, and have to be truncated after removing the job from the client cups' queue. Let me know if you need more info.
