Comment 1 for bug 1190097

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):
  File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 489, in _inline_callbacks
    result = gen.send(result)

    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
