Bug#725882: system-config-printer: freezes in New Printer dialog with UnicodeEncodeError in _unpack_getDevices_reply

[Zach Ploskey]

Package: system-config-printer
Version: 1.4.1-4
Severity: important

Steps to reproduce:
1. Run system-config-printer
2. Click the add button
3. Enter the password in the dialog
4. Wait a few seconds or try to use the dialogs

The widgets become unresponsive, though the window can still be moved. The
process has to be killed.

I receive this stack trace:
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 604, in
msg_reply_handler
    reply_handler(*message.get_args_list(**get_args_opts))
  File "/usr/share/system-config-printer/asyncpk1.py", line 115, in
_pk_reply_handler
    self._client_reply_handler (self._conn, self._unpack_fn (*args))
  File "/usr/share/system-config-printer/asyncpk1.py", line 442, in
_unpack_getDevices_reply
    result_str[str (key)] = str (value)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position
26: ordinal not in range(128)

It looks like the python code isn't handling the unicode correctly. Unicode
character (U+2019) is 'RIGHT SINGLE QUOTATION MARK'. The error occurs
regardless of whether I set LC_ALL=C as seemed to resolve another unicode issue
in #725799.
