system-config-printer-kde applet traceback with network printers configured

[Georg Brandl]

Binary package hint: kdeadmin

I have a printer configuration with several IPP network printers that I configured with the system-config-printer-kde applet from Kubuntu 9.04. In 9.10, when selecting the applet in the systemsettings app, it is stuck on the "server settings" view; one can't select any printers in the left-side treeview.

This traceback (also attached) is:

Traceback (most recent call last):
  File "/usr/share/kde4/apps/system-config-printer-kde/system-config-printer-kde.py", line 424, in on_tvMainList_cursor_changed
    self.fillPrinterTab(name)
  File "/usr/share/kde4/apps/system-config-printer-kde/system-config-printer-kde.py", line 1190, in fillPrinterTab
    self.fillPrinterOptions(name, editablePPD)
  File "/usr/share/kde4/apps/system-config-printer-kde/system-config-printer-kde.py", line 1234, in fillPrinterOptions
    ppd.markDefaults()
AttributeError: 'bool' object has no attribute 'markDefaults'

A little investigation showed: ppd in this case is False, it is assigned in this code (line 992ff here):

        try:
            self.ppd = printer.getPPD()
        except cups.IPPError, (e, m):
            # Some IPP error other than IPP_NOT_FOUND.
            self.show_IPP_Error(e, m)
            # Treat it as a raw queue.
            self.ppd = False

where printer.getPPD() returns False. It seems that this is always a possibility, because self.ppd can also set to False in the error handler shown above -- it seems to represent a remote IPP queue.

Could this be possibly a duplicate of bug #485867

nromal socket connected prionter work ok. It only fails for ipp-printers as described.

I can clearly confirm it on a fully updated lucid.

Confirmed on fully updated lucid kubuntu. Clicking away from a remote IPP printer also produces the following trace:
