I love these obsfucated error messages.  Apparently the df command is a simple
wrapper which either reads a file in /proc or runs a much more rudimentary
kernel probe type app and then reformats that input for human consumption.
(Actually, it looks like a two step process.  It first probes the kernel for a
list of mounted filesystem and then pipes that result into a routine which
probes each filesystem for usage info.)  Apparently the underlying process is
causing kernel warnings about unclean ext2 filesystems and df isn't quick
enough on the uptake to know that it's helper app crapped out.

Only on unix...
