system-config-printer can't open printer properties because job-cancel-after value is None

[jikamens]

I have system-config-printer 1.5.18-3 from Debian Testing. All my other CUPS etc. packages are up-to-date.

When I run system-config-printer, unlock it, and try to open the properties for a printer, nothing happens in the UI. In the terminal window from which I started system-config-printer I see a stack trace:

Traceback (most recent call last):
  File "/usr/share/system-config-printer/system-config-printer.py", line 597, in dests_iconview_item_activated

             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/share/system-config-printer/options.py", line 84, in OptionWidget
    v = int(v)
        ^^^^^^
TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType'

I modified printerproperties.py to indicate what option name and value are being processed right before this stack trace happens, and it said it was job-cancel-after with a value of None.

I don't know if this is the correct fix, but I made the problem go away with this change:

         except ValueError:

I suppose another option would be to change the except statement there from ValueError to (ValueError, TypeError).
