Your backtrace is a different one than I'd been expected from bug
#203784, so might not be fixed in 1.2.2-15.

It would be great if you could 'up' and 'info locals' at that point.
I think the following code is the problem;
1600 printercon = 0;
1601 printerfile = strstr(p->device_uri, "/dev/");
1602
1603 if (printerfile != NULL)
1604 {
1605 if (getfilecon(printerfile, &devcon) == -1)
1606 cupsdLogMessage(CUPSD_LOG_ERROR,
"cupsdSetPrinterAttrs: Unable to get printer context");
1607 else
1608 printercon = context_new(devcon);
1609
1610 if (context_range_get(printercon))
1611 rangestr = strdup(context_range_get(printercon));
1612 }
The call on line 1605 fails with -1, and so the context_new(devcon) on
line 1608 is never called, and that resultets in
(context_range_get(printercon)) on line 1610 to be called with a NULL
parameter, wich it apparently doesn't like.
