Title:
  Segfault with gir1.2-caribou-1.0 keyboard device info regression

Status in caribou package in Ubuntu:
  Fix Released
Status in caribou source package in Focal:
  Confirmed
Status in caribou source package in Groovy:
  Confirmed
Status in caribou source package in Hirsute:
  Fix Released

Bug description:
  It was found in cinnamon-screensaver that pressing ē can crash the
  screensaver and Cinnamon DE itself.

  This is a regression of solving CVE-2020-25712 (https://cve.mitre.org
  /cgi-bin/cvename.cgi?name=CVE-2020-25712) in xserver
  (https://gitlab.freedesktop.org/xorg/xserver/-/commit/87c64fc5b0db9f62f4e361444f4b60501ebf67b9)

  Supposed patch:
  https://gitlab.gnome.org/GNOME/caribou/-/merge_requests/3

  The following versions of Cinnamon are affected:
  4.4 - Focal
  4.6 - Groovy
  4.8 - Hirsute (unstable)

  Upstream caribou doesn't seem very maintained anymore. Hopefully patch
  will be put upstream so Hirsute can be solved. After that I will SRU
  Focal and Groovy.

  TL;DR: Caribou segfaults on pressing ē which can cause a screensaver
  bypass to cinnamon-screensaver and possibly any screensaver
  application using gir1.2-caribou-1.0.
