[Launchpad Bug Tracker <1400232@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package system-config-printer -
1.5.1+20141010-0ubuntu2.2

---------------
system-config-printer (1.5.1+20141010-0ubuntu2.2) utopic-proposed; urgency=medium

  * debian/patches/70_package-download-fixes.patch: Fixed several bugs to
    make automatic printer driver download working again (LP: #1401835):
     o Use pyrequests instead of pycurl for secure (verified certificate)
       downloads. pycurl stopped working after the OpenPrinting web server
       has moved from Ubuntu 10.04 to 12.04 (LP: #1394244).
     o In the install-printerdriver script improved the check for the
       necessity of adding the driver's Debian repository and added a
       workaround for a bug in aptdaemon interpreting PackageKit's package
       IDs wrongly when installing a package (LP: #1397750).
     o In fillDriverList() use ".hasattr()" to check presence of
       attributes.
     o Python3 transition bugs
  * debian/patches/73_support-non-utf-8-encoded-ppds.patch: Do not
    crash on non-UTF-8-encoded PPD files (LP: #1400232)
  * debian/control: Depend on python-requests instead of on python-pycurl.

  [Impact]

  It is impossible to set up or manipulate a printer with a PPD file
  which is not UTF-8-encoded and no plain ASCII. Even worse, if such a
  PPD is installed into the system's PPD repository, the corresponding
  printer(s) will not auto-setup.

  [Test Case]

  Take a PPD file which is not UTF-8-encoded, for example a PPD file for
  Windows with Windows-1252 encoding. Try to set up a que with it or to
  change an existing queue to use it by means of system-config-printer.
  system-config-printer will crash.

  With the proposed package the PPD can be used without problems.

  [Regression Potential]

  The changes are very simple and therefore the regression potential is
  low.
