Description of problem:
Nautilus shows contents of most directories just fine, however when trying to
view the contents of /usr nautilus just sits there with no screen
redraw and the nautilus-throbber spinning.  This goes on for several
minutes.

If the non-responsive window is destroyed, nautilus dies and then
restarts.  Seems like this is an issue when viewing directories with
lots of folders but not such an issue with directories that have lots 
of files (viewing /dev causes no problems).

Version-Release number of selected component (if applicable):
nautilus-2.4.0-5

How reproducible:
Always

Steps to Reproduce:
1. Open nautilus home directory by double-clicking on the desktop icon
2. Press the UP arrow and navigate to root directory
3. Double click the /usr folder icon
4. Listen to the fan turn on as the CPU gets eaten alive
