Title:
  segfault error 4 in libgobject-2.0.so.0

Status in update-manager package in Ubuntu:
  New

Bug description:
  == System information ==
  Ubuntu 23.10, up to date before today's updates.

  == Steps to reproduce (WIP) ==
  0. have a group of packages that are kept back from updating, plus some that aren't (screenshot demonstration attached) below
  1. open update-manager
  2. (try to) open the kept group, click on their (unchecked) checkboxes
  3. do the same for some of the other, non-kept packages
  4. repeat 2.-3. for a while

  == What happens ==
  Update-manager becomes unresponsive, then eventually segfaults:

      update-manager[3292]: segfault at 30 ip 00007fc0718b4c41 sp
  00007ffc2cca6a68 error 4 in
  libgobject-2.0.so.0.7800.0[7fc071889000+34000] likely on CPU 4 (core
  0, socket 0)

  == Other info ==
  I've marked the steps above WIP because these are the conditions under which I found this today, but I haven't yet tried narrowing them down, because of course I have little control over which updates are available and when. (For instance, the kept packages might just be a red herring.)

  I initially tried to report the crash file with ubuntu-bug, but despite asking preliminary questions, in the end it never opened a browser to complete the report. I'll try apport-collect next, but if that fails too, I'll just attach a crash file here manually.
