[cups.bugs] [HIGH] STR #1755: Web interface: "Set Printer Options" makes printer unaccessible

[Kurt Pfeifle]

[STR New]

A very peculiar behaviour of today's trunk build:

* Use web interface to "set printer options"
* Operation succeeds as indicated by 'Printer test-1ps has been configured
successfully.' message
* However, redirection back to the printer page doesn't succeed; web page
displays "Error:   Unknown"
* Printer will still be listed on "localhost:631/printers", even after
reloading
* However, printer will not appear on "localhost:631/printers/test-1ps"
* Relisting "localhost:631/printers" has printer present and enabled/idle
* Clicking on "Set Printer Options" of that printer gives again the
"Error:   Unknown"
* "lpstat -p test-1ps" succeeds as expected
* "lpoptions -p test-1ps -l" yields the message "lpoptions: Destination
test-1ps has no PPD file!"
* Checking printers.conf: printer is still there
* Checking /etc/cups/ppd/: PPD is still there
* Printing to this printer does not work; error_log (in debug mode) has
entries: 
     D [07/Jun/2006:02:37:44 +0200] Get-Printer-Attributes
ipp://localhost/printers/test-1ps
     E [07/Jun/2006:02:37:44 +0200] Get-Printer-Attributes: Unknown
* Send a hangup signal "kill -HUP $(pidof cupsd)" and everything works
again (including the display of the previously changed printer settings)
* Printing works fine again too
* Repeating that game will always have same results
* Setting the PPD options with e.g. "lpadmin -p test-1ps -o PageSize=A3"
works (result is correctly displayed in web interface).


This is reproducable every time I try it. This is the same for every
printer with a PPD.
