Description of problem:
This problem so far has been 100% reproducible.

1.  Run testdisk to try to recover a partition.
2.  The process runs to around 87%
3.  testdisk crashes at around 87%, throwing this error.

Also accompanying the error was an SELinux denial when it tried to write to the system log.

I set enforcing to 0 and the SElinux error does not occur but the app still crashes whether I choose to have it log what it finds or not.  It finds the lost partition and even gives the correct name in the first output but the application never finishes without crashing out and I cannot recover the lost data because the application never gets to that point.

It is something that keeps throwing arithmetic exceptions involving recovery of ext2.  I am not using it to recover ext2, just ntfs, HFS+ and EFI, so I am not sure why I am seeing that.
