the problem is if I connect with
 obexftp -b [mybluetoothnetworkid] -l
Browsing [mybluetoothnetworkid] ...

but with
obexftp -b [mybluetoothnetworkid] -B 12 -l

Browsing [mybluetoothnetworkid] ...
Channel: 10
Connecting...done
Receiving "(null)"... <?xml version="1.0"?>
<!DOCTYPE folder-listing SYSTEM "obex-folder-listing.dtd"

   <folder name="E:" user-perm="RW" mem-type="MMC" label="Nick"/>
</folder-listing>done
Disconnecting...done

and I can browse the files...

my question is how I can put a -B 12 options in gnome-vfs-obexftp?
and if I type in prompt

gnomevfs-ls 'obex://[mybluetoothnetworkid]/E:/Images'

it display correctly the directory listing
but if I open the same string in nautilus with
nautilus 'obex://[mybluetoothnetworkid]/E:/Images'

it said somewhat like (I have italian localized version)

it's not possible to display <<obex://[mybluetoothnetworkid]/E:/Images>>
