[Utopia] Gnome-VFS backend crashing file chooser dialog

["John (J5) Palmieri" <johnp redhat com>]

I was wondering if anyone else is seeing this. Using the latest patch
from Dave it seems that clicking on any of the volumes in the shortcut
window of the file chooser causes a crash.  This has been seen by others
who use my patch packages.  I have been trying to track it down at I
know the crash happens at a strcmp in shorcut_find_position where
base_path is NULL.  This is because the volume data that was populated
into the shortcut's list model became invalid at some point.  I tracked
it down to the fstab and the mtab lists of the vfs daemon somehow
trashing its own data.  Beyond that I can't figure out where the
trashing is actually happening.  Below is a backtrace of the symptom
with the last unknown symbol being the strcmp.  Hopefully someone can
add some insight.
