Hi, I am attempting to rescue a deleted ext3 partition.  The deleted 
partition was hda11 and started at 5006*8225280.  Here is what I 
get (with latest parted):

parted /dev/hda

Segmentation fault

It actually does not matter the start location, no matter what I choose
the result is always a segv.  Using valgrind the problem is shown to be 
here:
