Loading IM context type 'ibus' failed

[liufeng4080]

Regression issue caused by recent system updates on Ubuntu 20.04 Focal Fossa (development branch)

Many(or to say, most) applications,like eclipse,lazarus,gnome-shell,gedit... reported below error in syslog or console as,
...
(lazarus-ide:20387): Gtk-WARNING **: 00:11:55.562: Loading IM context type 'ibus' failed
(lazarus-ide:20387): Gtk-WARNING **: 00:11:55.566: GModule (/usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/immodules/im-ibus.so) initialization check failed: GLib version too old (micro mismatch)
...

and Pinyin input method does not work in these applications.

Symptom occurs since I updated below 17 packages some hours before,
gir1.2-ibus-1.0
gvfs
gvfs-backends
gvfs-bin
gvfs-common
gvfs-daemons
gvfs-fuse
gvfs-libs

ibus-gtk
ibus-gtk3
libglib2.0-0
libgtk-3-0
libgtk2.0-0
libibus-1.0-5

current versions of above packages are,

Thanks for your report! I could reproduce the problem, which is a bit weird because IBus was updated yesterday and the IBus input methods I tested worked fine then...

Anyway, I see in the error message: "GLib version too old". So I upgraded the libglib2.0-* packages to version 2.64.0-1 (from focal-proposed) and that fixed the issue.

So it looks like we just need to be patient and wait for libglib2.0-* to migrate to focal-release.

Symptom unreproducible after glib upgraded to proposed libglib2.0-0/focal-proposed,now 2.64.0-1 amd64 [installed].

[Gunnar Hjalmarsson (gunnarhj)]

glib2.0 2.64.0-1 migrated to -release. Closing this bug.

[Gunnar Hjalmarsson (gunnarhj)]

Reopening the ibus task, since there is a fix in Debian which will prevent this issue from showing up going forward.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ibus - 1.5.22-2ubuntu1

---------------
ibus (1.5.22-2ubuntu1) focal; urgency=medium

  * Merge from Debian unstable (LP: #1865907). Remaining changes:
    - d/p/ubuntu-disable-trigger.patch
    - d/p/ubuntu-forward-panel-properties.patch
    - d/p/ubuntu-unicode-keybinding.patch
    - d/rules, d/control: use dh_translations
    - Add breaks for older libglib2.0-0 releases which do not contain
      the GDBusServer fix for Qt applications

ibus (1.5.22-2) unstable; urgency=medium

  [ Changwoo Ryu ]
  * Revert the emoji-test.txt embedding and use emoji-test.txt in
    unicode-data (>= 13.0.0-2), which ships this file (#953795).
  * debian/patches/libexec-fhs2-compat.patch: Provide compatibility with
    FHS 2.x built ibus engine packages, after moving to /usr/libexec
  * debian/rules: Set GVFS_DISABLE_FUSE=1 while running tests, to prevent
    gvfsd from mounting FUSE filesystems.
  * debian/patches/remove-glib-check-version.patch: Do not check glib
    runtime version on gtk immodule init. (Closes: #954207)
  * debian/ibus.bug-script: Updated
    - Use /bin/sh instead of /bin/bash
    - Remove locale/shell envvars which are redundant (See #946326)
    - Add more settings from GSettings, localectl, setxkbmap and ~/.Xmodmap
      (Closes: #942470)

  [ Laurent Bigonville ]
  * Move the daemons to /usr/libexec now that's allowed in the policy

ibus (1.5.22-1) unstable; urgency=high

  [ Changwoo Ryu ]
  * debian/lintian-overrides: Ignore lintian info
    hardening-no-fortify-functions on /usr/bin/ibus-daemon. It uses
    readlink(2) which is not protectable.
  * debian/copyright: Correct copyright years and add new files
  * Fix FTBFS with unicode-data 13.0 (Closes: #953775)
    - debian/emoji/emoji-test.txt: Added in the source, downloaded from
      https://www.unicode.org/Public/emoji/13.0/.
    - debian/README.source: Add information on it
    - debian/copyright: Add Unicode license
    - debian/rules: Add --with-unicode-emoji-dir flag
  * debian/control: Update Build-Depends
    - The upstream requires GTK 3.12.0

  [ Laurent Bigonville ]
  * debian/control: Add libglib2.0-doc to the Build-Depends-Indep. This
    will fix the link between the ibus documentation and the GLib one
