[Bug 1190097] Re: Nautilus tries but fails to auto-install applications needed to open files of a given type

[Sebastien Bacher]

Thanks Adam, trying to figure out what is happening there I looked at a
dbus-monitor log and saw that:

"error sender=:1.444 -> dest=:1.438 error_name=org.freedesktop.DBus.Python.xdg.Exceptions.ParsingError reply_serial=158
   string "Traceback (most recent call last):

    path))
  File "/usr/lib/python2.7/dist-packages/xdg/DesktopEntry.py", line 33, in __init__
    self.parse(filename)
  File "/usr/lib/python2.7/dist-packages/xdg/DesktopEntry.py", line 42, in parse
    IniFile.parse(self, file, ["Desktop Entry", "KDE Desktop Entry"])
  File "/usr/lib/python2.7/dist-packages/xdg/IniFile.py", line 81, in parse
    raise ParsingError("Invalid line: " + line, filename)
ParsingError: ParsingError in file '/usr/share/app-install/desktop/workrave:workrave.desktop', Invalid line: - RSI (Repetitive Strain Injury) oraz wspomaga rekonwalescencj\u0119"

removing '/usr/share/app-install/desktop/workrave:workrave.desktop'
fixes the issue

I'm adding app-install-data-ubuntu (which ships the broken .desktop),
workrave (where the original .desktop comes from) and sessioninstaller
(which shouldn't probably stop working because one file has parsing
errors) to the affected components

Bug description:
  I'm running Nautilus 3.6.3 on Ubuntu 13.10 (Saucy).

  When I double click a file in Nautilus and there is no application
  installed which can open the file, Nautilus will try to auto-install
  an application but the auto-install hangs.  Specifically, for example:

  1. Make sure that Gnumeric is not installed on your system.
  2. Create a file with extension .gnumeric and double click it in Nautlius.

  Nautilus will report:

    Could not display "finance.gnumeric".
    There is no application installed for "Gnumeric spreadsheet" files.
    Do you want to search for an application to open this file?

  Click Yes.  You'll now see a dialog that looks like this:

    Searching for suitable software to open files
    Files requires to install [sic] software to open files of the following file type: Gnumeric spreadsheet

  The dialog has a progress bar, which will briefly pulse and then stop.
  You can now only press Cancel.

  A glance at the code shows that Nautilus is trying to send a DBus
  message to PackageKit to perform the install.  There are apparently
  some PackageKit components on my system (e.g. libpackagekit-glib2-14
  is installed), but something is not working.
