I think I got hit by this problem too.

Fedora 16
# e2fsck -V
e2fsck 1.41.14 (22-Dec-2010)
	Benutze EXT2FS Library version 1.41.14, 22-Dec-2010

The device is definitely not mounted.

However I can mount and use the device as usual. Just once I umount it (and it is not listed any more on /proc/mounts), I can not run e2fsck on it.
