running budgie-desktop without ibus installed causes desktop to crash

[fossfreedom]

[ Impact ]

 * Where ibus has been manually uninstalled, budgie desktop will crash
   This is a regression in Jammy due to the SRU patch applied in
   issue #1956240

[ Test Plan ]

 * Test that ibus-daemon is running
   ps -ef | grep ibus-daemon
   if the process is running then proceed with the test plan
   if the process is not running then install ibus, logout and login
   to test that ibus-daemon is indeed running
 * 1) on login open a terminal (CTRL+ALT+T) or an application and type a character such as the quote key or the currency key.
 * If the quote key defaults to something else such as the @ key or the currency key defaults to $ then you have a default layout of en_US.
 * Add the keyboard layout applet to your panel
 * from the list provided choose another keyboard layout
 * Repeat test step "1)" above. Check that your chosen keyboard layout is correctly applied.

 * from the proposed repo install the following packages:

   sudo apt update
   sudo apt install budgie-desktop budgie-core libbudgie-plugin0 libbudgie-private0 libbudgietheme0 libraven0 gir1.2-budgie-1.0

 * Logout and login

 * Repeat the above testing again - on login your expected layout should be applied e.g. en_GB if that was your last chosen layout.
 * Lastly purge ibus
   sudo apt purge ibus
 * logout and login
 * check that the first keyboard layout is applied

[ Where problems could occur ]

 * Primarily the key issue is introducing a stability issue on budgie such as crash on login.
 * Additionally the other issue is introducing a regression in applying keyboard layouts for more people rather than eliminating the issue.
 * As such this fix has been iteratively developed through a multi-month testing regime with multiple community team members

https://discourse.ubuntubudgie.org/t/cant-change-keyboard-layout/5293

[ Other Info ]

 * This issue is specifically for Jammy - it backports the same patch
   already applied in lunar/kinetic to Jammy - hence the UB team
   regard this as well tested since it is now more than a month since
   release on 22.10 and no reported issues here on launchpad or on
   our discourse forum.

Regression noted for the budgie-desktop (jammy) -ubuntu2 upload.

For installs that have manually decided to uninstall ibus (and therefore removed ibus-daemon) - budgie-desktop crashes.

This is a regression from -ubuntu1~22.04 where such desktop installs did not crash
