Known problem, fixed in e2fsprogs 1.42.2 or 1.42.3 in commit:

commit 3d6fc974831a360aee460e54c442538445f3017c

    resize2fs: fix crash when there is an ea block and no blocks to migrate

    This fixes a bug introduced in 1.43 by commit fb47b94fffc: "resize2fs:
    rewrite extent/dir/ea block checksums when migrating". If there is an
    extended attribute block and there are no blocks that need to migrate,
    we will crash.

    The bug was caused by a botched De Morgan's transformation.

    Signed-off-by: Theodore Ts'o <email address hidden>

Note that e2fsprogs 1.43.3-1 is in Debian unstable, and the only reason why it's blocked from entering testing for the last three weeks is because of the glibc 2.24 transition.

[Mathieu Trudel-Lapierre (cyphermox)]

This bug was fixed in the package e2fsprogs - 1.43.3-1

---------------
e2fsprogs (1.43.3-1) unstable; urgency=medium

  * Fix e2fsck's handling of timestamps on 32-bit system (Closes: #836559)
  * E2fsck will sanity check and repair the extra isize fields in inodes
    and the superblock.
  * Fix sparc64 crashes when dereferencing unaligned integers in journal
    blocks when metdata checksums are enabled.

e2fsprogs (1.43.2-2) unstable; urgency=medium

  * Fix build reproducibility problems
  * Don't hide the linker flags for e2fsck.static

 -- Theodore Y. Ts'o <email address hidden> Thu, 01 Sep 2016 23:30:55 -0400

e2fsprogs (1.43.2-1) unstable; urgency=medium

  * Change the default journal size to be larger for file systems larger
    than 128 GB to improve performance on metadata-heavy workloads
  * Clarify tune2fs's message when the user needs to run e2fsck
    (Closes: #828022)
  * Fix an alignment bug in e2fsck which caused sparc64 architectures to
    crash when replaying the journal on file systems with a 64-bit block
    number
  * Fix a typo in debugfs when printing out the dtime field on file
    systems with an extended timestamp
  * Fix the logic in e2fsck which decides when to repair legacy negative
    timestamp encodings.
  * Add a command to debugfs to copy the inode structure from one inode
    to another
  * Fix resize2fs so it will not crash if there is an extended
    attribute block but it doesn't need to migate any blocks during
    an off-line resize
  * Fix a crash when mke2fs or debugfs tries to copy in a directory
    hierarchy containing an empty directory
  * Fix a bug in e2fsck caused by a power failure during e2fsck's journal
    replay could leave the file system in a state where if the file
    system is mounted without doing a full e2fsck scan, the file system
    could get corrupted
  * Fix big endian bugs in the e2undo program
  * Fix debugfs's logdump so command so it can correctly handle journals
    which are larger than 2GB
  * Add new translations: Hugarian and Serbian
  * Update the Catalan, Chinese, Danish, Dutch, French, German, Polish,
    Swedish, Ukrainian translations
