there is another problem reported by community member related to this bug:
(original source: https://bugzilla.redhat.com/show_bug.cgi?id=1373206)

Description of problem: I dumped my new system after upgrading to Fedora 24, I tried to recover a file from the dump image today. Huge amounts of "Incorrect block for <file removal="" list=""> at NNNN blocks" appear. The dump file is not usable.

dump-0.4b45

How reproducible: 100% - I tried to see if restore worked on any of the file systems (root, boot, home) - same problems with each. Prior dumps made with previous dump work fine using newer restore.

Steps to Reproduce:
1. put in a mountable disk, change directory to somewhere on it
2. e.g. - boot is small so only one volume
dump -u0 -f - -A boot.toc -L boot -z2 /boot | split -b 2GB -d - boot.dmp
3. restore if boot.dmp00
other file systems require a line like the below
cat root.dmp* | restore if -

Actual results:
Dump tape is compressed.
Incorrect block for <file removal="" list=""> at 19 blocks
Incorrect block for <file removal="" list=""> at 20 blocks
..... two thousand times
Incorrect block for <file removal="" list=""> at 2057 blocks
Incorrect block for <file removal="" list=""> at 2058 blocks
decompression error, block 2059: data error
File decompression error while restoring <file removal="" list="">
continue? [yn]

Expected results:
Dump tape is compressed.
restore >

----- END -----

this "Incorrect block.." message was added by patch mentioned in bug report attachment. It looks that real problem wasn't resolved, but just highlighted.
