I have verified the testcase on eoan using version 2.62.4-1~ubuntu19.10.1 of the libglib2.0-* packages from eoan-proposed and version 1.5.21-1~exp2ubuntu2.1 of the ibus packages from ppa:ubuntu- security-proposed/ppa.

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.
