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)
...
