My read of the postinst is that it correctly chmod's /var/crash
regardless of whether it did the creating:

                mkdir -p -m 3777 /var/crash
                chmod g+s /var/crash
                chgrp whoopsie /var/crash


I've confirmed that 'mkdir -p -m' doesn't change the mode of an existing directory.  And /var/crash has been on my system since 2019 when this system was installed, so it's not new here?

Running `dpkg-reconfigure whoopsie` (i.e., triggering a rerun of the
postinst) is sufficient to fix the directory permissions.

But it must have been something else besides the apport postinst that
dropped the g+s bit.

Title:
  apport-gtk keeps prompting to report crashes in a loop

Status in apport package in Ubuntu:
  Confirmed

Bug description:
  /var/crash has the following contents:

  -rw-r----- 1 vorlon   vorlon   107490 May 23 16:05 _usr_bin_gourmand.1000.crash
  -rw-rw-r-- 1 vorlon   vorlon        0 May 23 16:06 _usr_bin_gourmand.1000.upload
  -rw------- 1 whoopsie whoopsie      5 May 23 16:07 _usr_bin_gourmand.1000.uploaded
  -rw-r----- 1 vorlon   vorlon    23647 May 23 13:57 _usr_bin_python-argcomplete-check-easy-install-script.1000.crash
  -rw-rw-r-- 1 vorlon   vorlon        0 May 23 13:59 _usr_bin_python-argcomplete-check-easy-install-script.1000.upload
  -rw------- 1 whoopsie whoopsie      5 May 23 13:59 _usr_bin_python-argcomplete-check-easy-install-script.1000.uploaded

  As seen, the .upload / .uploaded files were created within 2 minutes
  of each of the crashes.

  But after submitting the crash report for /usr/bin/python-argcomplete-
  check-easy-install-script, I left my desktop for a while.  I came back
  to find at least TWENTY dialogs prompting me to submit the same crash
  report.

  The only way to stop the system from creating more prompts is to
  remove these files from disk.
