The fix is verified in Saucy. I was able to install Canon MP160 and
print a test page without any problems.

Bug description:
Installing driver for Canon MP160 has worked perfectly from 12.04 to
13.04, but not anymore in 13.10. The USB printer get detected
correctly, but when installing the driver via "New Printer" dialog,
only gutenprint can be selected and the "Installing driver gutenprint"
dialog just gets stuck and nothing happens.
[IMPACT]
High, as if locally unsupported printers cause a driver download from
OpenPrinting the download ends in an infinite loop and cannot be
cancelled due to a crashed user interaction thread, blocking system-
config-printer completely not allowing a manual setup of the printer.
[TESTCASE]
In a terminal window run the commands
cd /usr/share/system-config-printer/
python newprinter.py --setup-printer=file:/tmp/printout
--devid='MFG:Canon;MDL:MP160;'
Accept to download the offered Gutenprint driver and enter your
password when you get asked for it. The download and installation of
the Gutenprint package from OpenPrinting will take place and right
after that, before closing the progress pop-up, system-config-printer
will freeze.
In the terminal output of above commands you can see a crash of one
thread:
----------
Traceback (most recent call last):
File "/usr/share/system-config-printer/newprinter.py", line 3676, in
on_tvNPDownloadableDrivers_cursor_changed
iter = model.get_iter (path)
File "/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py", line 810, in
get_iter
path = self._coerce_path(path)
File "/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py", line 785, in
_coerce_path
return TreePath(path)
File "/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py", line 1135, in
__new__
path = ":".join(str(val) for val in path)
TypeError: 'NoneType' object is not iterable
----------
Due to this task you cannot get out of the printer setup wizard by
clicking "Cancel".
With the proposed system-config-printer package neither the crash nor
the freeze will happen and both setting up the printer with the
package from OpenPrinting and canceling the OpenPrinting download and
after that setting up the printer manually will work.
[Regression Potential]
None, as the patch is trivial
