[STR New]

I've a little program running as root whose job it is to call
cupsGetJobs(&jobs, NULL, 0, CUPS_WHICHJOBS_ALL) once an hour and call
cupsCancelJob() for any job which has been held for 24 hours or more.
(This to keep our job queue clean.) It works fine with 1.3.*, but for a
1.4b2 test installation I'm getting the return value -1 and the error "The
printer or class was not found."

The source code in question is:

	/* Cancel any jobs which have been held for more than the configured
	 * maximum hold time. E-mail the user to tell them what has happened.
	 */
	age = printerconfig[maxJobHoldDuration].i;
	firsttime = time(NULL) - age;
	num_jobs = cupsGetJobs(&jobs, NULL, 0, CUPS_WHICHJOBS_COMPLETED);
	startlogline(level(printerconfig[logLevel].s), debug,"num_jobs %d\n",
num_jobs);
	if (num_jobs >= 0) {
		for (i = 0, job = jobs; i < num_jobs; i++, job++)
			if (job->state == IPP_JOB_HELD && job->creation_time < firsttime) {
				startlogline(level(printerconfig[logLevel].s), info,
					"Canceling %s-%d (%s) queued by %s at %d ...\n",
					job->dest, job->id, job->title, job->user,
					toisotime(job->creation_time, isotimebuf));
				cupsCancelJob(job->dest, job->id);
				informuser(level(printerconfig[logLevel].s),
printerconfig[sendmailPath].s,
					job->user, job->dest, job->id, job->title, 
					printerconfig[describeMaxDuration].s,
					printerconfig[chargeDocURL].s,
					printerconfig[CUPSJobsPageURL].s,
					printerconfig[supportEmail].s);
			}
		cupsFreeJobs(num_jobs, jobs);
	} else
		startlogline(level(printerconfig[logLevel].s), info,
				"cupsGetJobs() returns num_jobs %d error \"%s\"\n", num_jobs,
                               cupsLastErrorString());
