Bug#486580: system-config-printer: Can't change printer settings

[Sam Morris]

Package: system-config-printer
Version: 1.0.0-1
Severity: important

When trying to change the description of a printer, after pressing OK I
am prompted to authenticate. After I do so, system-config-printer locks
up, but in a strange way: controls on the screen still operate, but the
OK/Cancel buttons do nothing.

The console contains the following message:

Traceback (most recent call last):
  File "/usr/share/system-config-printer/contextmenu.py", line 115, in on_printer_context_edit_activate
    self.parent.dests_iconview_item_activated (self.iconview, self.paths[0])

    if not self.save_printer (self.printer):
