This causes the following to just loop over and over, incrementing the
pid:

gnome-vfs-daemo(8914): 
gnome-vfs-daemo(8914): /
gnome-vfs-daemo(8914): /proc
gnome-vfs-daemo(8914): /sys
gnome-vfs-daemo(8914): /dev
gnome-vfs-daemo(8914): /dev/pts
gnome-vfs-daemo(8914): /dev/shm
gnome-vfs-daemo(8914): /proc/bus/usb
gnome-vfs-daemo(8914): /proc/sys/fs/binfmt_misc
gnome-vfs-daemo(8918): 
gnome-vfs-daemo(8918): /
gnome-vfs-daemo(8918): /proc
gnome-vfs-daemo(8918): /sys
gnome-vfs-daemo(8918): /dev
gnome-vfs-daemo(8918): /dev/pts
gnome-vfs-daemo(8918): /dev/shm
gnome-vfs-daemo(8918): /proc/bus/usb
gnome-vfs-daemo(8918): /proc/sys/fs/binfmt_misc

and so on...

I'm running gnome-vfs version 2.6.13 if that matters.

Anything else I can try?

thanks,
