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
  File 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.
