Just added the ubuntu-desktop ppa and updated. Got the following updates:
------------------
The following packages will be upgraded:
  gtk2-engines-pixbuf libgail-common libgail18 libgtk2.0-0 libgtk2.0-bin
  libgtk2.0-common libnautilus-extension1 nautilus nautilus-data
9 packages upgraded, 0 newly installed, 0 to remove and 23 not upgraded.
Need to get 16.9MB of archives. After unpacking 20.5kB will be used.
Do you want to continue? [Y/n/?] y
-------------------
On restart, I can no longer navigate using nautilus. Using the sidebar to navigate is unresponsive and clicking on folders gives a pop up message: "opening 'folder' you can stop this operation by clicking cancel" the folder however, never opens.
