no.. i know i have plenty of available space.  i am just going to unmount
the partition (unfortunately its /home) asap, and run e2fsck on
it.  however, i am still very much interested in what caused this, and if
it could be replicated.  because this could be a possible root hole in
ext2, although how i would find out more about exploiting this i dont
know.  all i know is that a segfault is probably exploitable.  Thanks
all for the help though :)
