Bug#494492: nautilus "filesystem" in tree view keeps dissappearing

[Mark Ryan]

Package: nautilus
  Version: 2.20.0

While using nautilus for random tasks, after the File System choice in the left hand window "tree view" disappears totally.
I have to close and restart nautilus to get the file system back.  When this happens, I only have access to my home dir and the mounts below it.

I'm using Debian Lenny current as of 8/9/2008
