debugfs crashed with SIGFPE in ext2fs_open2()

[Pazkooda]

Binary package hint: e2fsprogs

My filesystem crashed for unknown reason. While trying to fix it with fsck I reveived "Unsupported features..." message.
So according to forums I've tried to perform actions to disable them by tune2fs (no superblock found - no fix) and then with debugfs calling:

sudo debugfs -w -R "features ^resize_inode ^dir_index" /dev/sda5

This leads to:
Floating point exception (core dumped)
on terminal and Apport notification.

Additional note:

All steps performed from Karmic Live CD. System on HDD is Jaunty (ext3 fs).
Apport suggest to upgrade some packages after first failure (libc6 and related). After sudo aptitude install <list of suggested packages> issue persists. This bug report comes from "upgraded" LiveCD.

Hie Pazkooda! If you do still have the image with you, then can you please attach the output of sudo tune2fs -l /dev/sda5 ? Thanks!
