[cups.bugs] RE: [LOW] STR #1774: Add printer wizzard and auto-discoverred shows different list of printers

[George Liu]

There probably IS a memory accessing problem in CUPS 1.2.
Please keep this bug Open.

>From Add Printer Wizzard (APW), some printers are listed as Unknown.
Those unknown printers have been auto-discovered (with valid manufacture
and model name)

Way to reproduce:
1. Click Administration. A list a printers will be discovered.
2. Click Add Printer, provide a name and examine the printer drop down
box. (In many cases, there'll be printer named "Unknown". The unknown
printers have been discovered in the previous step.)
3. Click the back button to the main page of administration. Click Add
Printer and check the printer list again. Printers of different IP
addresses would be marked "Unknown". This list most likely is not the
same as the printer in step 2.

I have roughly 20 printers in my subnet.
