Bug#854497: ext4magic: SIGSEGV while recovery from encrypted USB stick

Package: ext4magic
Followup-For: Bug #854497
X-Debbugs-Cc: markusba...@users.sourceforge.net

Dear Maintainer,

the program segfaults with a similar backtrace during directory listing. I 
think the local_ext2fs_extent_free() function iterates one to far.
However, following the changes from the patch for Bug #802089 using the 
original ext2fs_extent_free() function here should be appropriate. It fixes it 
for me.
