I have seen this apparently provoked by an lpq(1) command, which got:

$ lpq -Ppp23
/usr/bin/lpq: Permission denied
$

but an immediately following lpq(1) worked:

$ lpq -Ppp23
pp23 is ready
no entries
$

If (iff?) I have Print-URI in cupsd.conf, I see instead:

I [11/Mar/2008:15:34:39 +0000] cupsdCloseClient: SSL shutdown successful!
E [11/Mar/2008:15:34:39 +0000] Bad URI "gibberish" in request!
D [11/Mar/2008:15:34:39 +0000] cupsdSendError: 8 code=405 (Unknown)

Neither seem to do any lasting harm. Perhaps this is not solid enough to be an STR.
