Bug#819284: jessie-pu: package ext4magic/0.3.2-2

Severity: normal

Hi!

The ext4magic has a misinterpretation of the physical block addresses and
block lengths of ext4 inode.
The error is permanent and 100% reproducible (also on i386)
The upstream provides a patch to fix this problem and this problem has
been fixed en unstable/testing.

The changelog is:

ext4magic (0.3.2-2+deb8u1) jessie; urgency=medium

  * debian/patches/fix-recover-examine.patch: added as a temporary work
  around to fix an issue which makes impossible to recover or examine
  Ext4 filesystems. Thanks to Roberto Maar , the
  ext4magic upstream. (Closes: #802089)
