[Bug 2081708] Re: Incompatible with systemd zstd coredumps (could not determine content size in frame header)

[Launchpad Bug Tracker]

This bug was fixed in the package apport - 2.31.0+git20250220-0ubuntu1

---------------
apport (2.31.0+git20250220-0ubuntu1) plucky; urgency=medium

  * New upstream snapshot
    - ui: skip value not empty check in get_complete_size (LP: #2081708)
    - problem_report: use an iterator in CompressedValue.__len__ to keep
      the memory footprint small (LP: #2081708)
    - apport-gtk: check for available display on startup (LP: #2006981)
  * Drop patches that were applied upstream
  * Apply patches that are pending upstream:
    - Split __AptDpkgPackageInfo.install_packages() into smaller methods
    - fileutils: refactor core_name in get_core_path and add type hints
    - test: some refactoring and fix test_find_package_desktopfile_multiple
  * Build-depend on python3-pyqt5 for ui_kde integration tests
  * autopkgtest:
    - depend on apport-gtk and apport-kde for new UI integration tests
    - install xterm for test_find_package_desktopfile_multiple

Title:
  Incompatible with systemd zstd coredumps (could not determine content
  size in frame header)

Status in Apport:
  Fix Committed
Status in apport package in Ubuntu:
  Fix Released

Bug description:
  zstd.ZstdError: could not determine content size in frame header

  I have systemd-coredump and python3-zstandard installed.

  This is fixable by passing a max_output_size parameter to the decompression method:

  The backtrace:
