I have verified the testcase
- on bionic using version 2.56.4-0ubuntu0.18.04.5 of the libglib2.0-*
packages from bionic-proposed and version 1.5.17-3ubuntu5.3 of the ibus
packages from ppa:ubuntu-security-proposed/ppa
- on xenial using version 2.48.2-0ubuntu4.5 of the libglib2.0-* packages
from xenial-proposed and version 1.5.11-1ubuntu2.4 of the ibus packages
from ppa:ubuntu-security-proposed/ppa
As regards the autopkgtest failures, please see comment #29.
Marked the disco bug task as "Won't Fix" since disco is EOL.

Bug description:
[Impact]
IBus was broken for Qt applications as a regression due to the fix of
CVE-2019-14822. As a result the IBus patch was disabled temporarily,
which fixed IBus from a usability POV.
The real fix has been made in glib2.0, and the updates in -proposed
will allow the IBus patch to be re-enabled.
[Test Case]
* On a standard Ubuntu {eoan,disco,bionic,xenial} installation
- Upgrade the glib2.0 packages from
{eoan,disco,bionic,xenial}-proposed
- Upgrade the ibus packages from
https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa
- Install some IBus input method, e.g. ibus-libpinyin
- Install some Qt application, e.g. Kate
* Relogin (maybe reboot)
* Add the input method to the input sources
* Open the Qt app and try to input something using the IBus IM
=> Find that the transliteration works as expected
[Regression Potential]
The applicable patches origin from glib upstream:
https://gitlab.gnome.org/GNOME/glib/merge_requests/1176
Consequently the changes have been reviewed by the glib maintainer, but also
tested by the IBus maintainer, by me (gunnarhj), and - of course - the author
Simon McVittie. The changes have been in Debian unstable since 2019-10-30.
[Original description]
Kubuntu Release 18.04.3 LTS
Expected behavior:
ibus continues working as before after applying security update
1.5.17-ubuntu5.1 from version 1.5.17-ubuntu5.
Observed behavior:
ibus is not usable anymore in Qt applications.
After updating ibus and the related packages ibus-gtk, ibus-gtk3,
libibus-1.0-5 and gir1.2-ibus-1.0 all from version 1.5.17-ubuntu5 to
1.5.17-ubuntu5.1, I can no longer use ibus in Qt applications. Using
shift-space no longer changes the selected input method and even when i switch
to the mozc input method in a gtk application, i can not use it in any Qt
applications.
When starting qtconfig in a terminal, I also get the following message:
Bus::open: Connect ibus failed!
IBusInputContext::createInputContext: no connection to ibus-daemon
This bug was not present in version 1.5.17-3ubuntu5 and I also
confirmed that downgrading the packages to version 1.5.17-3ubuntu4
restores ibus functionality in Qt applications.
