[Extundelete-users] Segmentation Fault

[<ext...@li...>]

I am repeatedly running into Segmenation Faults while running EXTUndelete on a variety of test images I have (both ext3 and 4 stored as raw images). To access the partitions, I first run kpartx. I then run extundelete on the partition in /dev/mapper/loopXpX.
I am running 64 bit Xubuntu v 12.10.
Extundelete version: 0.2.0
libext2fs version: 1.42.5

In the crash report, under Title, I see this:
extundelete crashed with SIGSEGV in ext2fs_extent_get()

Here is the execution and output:

:/home/user/Desktop/extund2# extundelete /dev/mapper/loop0p5 --restore-all
