It appears that something failed getting the file system values.  Try
debugging this using strace.  The following produces useful debug
output on my GNU/Linux system for usb storage devices.

  LC_ALL=C strace -v -e fstat64 df -l

Please run that, making whatever adjustments needed for your system,
and report the results back to the mailing list.  I suspect that the
system call is failing.  If so then this is a kernel issue since the
kernel implements the underlying interface to the usb storage media.

That is quite an old version having been released on 2005-01-08.  The
current release is coreutils 6.9 from 2007-03-22.  See this release
annoucement for more information.

  http://lists.gnu.org/archive/html/coreutils-announce/2007-03/msg00000.html

Details of obtaining the latest GNU coreutils are in the release
announcement.  Or since you are using a vendor supplied version you
might check with your vendor for updates and bug fixes.
