Description of problem:
I had this .ppt file and when double clicked I realized I had no openoffice, so I followed the hint to search for an application.
Obviously, being openoffice, it took ages to download and install. Somewhere during the process I saw an ugly warning dialog saying that the operation failed because the message bus timed out (although the installation kept going, the original "search" died).

Version-Release number of selected component (if applicable):
PackageKit-yum-plugin-0.4.6-2.fc11.i586
PackageKit-glib-0.4.6-2.fc11.i586
PackageKit-gstreamer-plugin-0.4.6-2.fc11.i586
gnome-packagekit-2.27.1-1.fc11.i586
PackageKit-gtk-module-0.4.6-2.fc11.i586
PackageKit-0.4.6-2.fc11.i586
PackageKit-yum-0.4.6-2.fc11.i586

How reproducible:
Once, but I suspect always.

Steps to Reproduce:
1. Double click a file in nautilus that has no handler, in my case a ppt when I had no openoffice installed
2. Search for a handler, accept to install it.
3. Wait until somewhere after a long time, the original "search" notifies you that it failed because of a message bus timeout, but the installation keeps going and ends succesfully.
  
Actual results:
A scary message bus timeout -operation failed- message

Expected results:
No scary message

+ Info:
After ooo-impress was installed, the file did not launch, I suspect this is because the "original operation" (the search) died, so the install was completed but no one was watching it to do something after it.
