OS: Leap 42.1 Milestone 1
PC: Intel Core2Duo

Summary:
When I tried to install our networked Canon iR C5235i printer through Yast's
"Printer" module, I was never able to successfully complete the installation
when choosing my local PPD file. Yast told me that CUPS is restarting, and
after waiting the recommended 30s, the module returned to the "Printer
Configurations" screen showing no printers.

Details:
1. Use Yast's "Printer" module, go to "Printer Configurations", "Add"
2. Specify a connection (socket, <IP>, port 9100) and test it (= OK), choose
"canon" printer model
3. Use "Find More", load PPD from local file system
4. Yast is restarting CUPS, wait for 30s.
5. Setup seems to complete OK, but Yast returns to initial screen ("Printer
Configurations"), no configuration entry is shown.

Tried 2 times, same result.

Workaround:
Use CUPS web interface to add the printer, using the same local PPD produces a
working printer queue.
