iBus installed w/ Chinese Pinyin but "[Invalid UTF-8]" results on selection of characters

[Cedric Bhihe]

Platform: Linux xxx 3.13.0-27-generic #50-Ubuntu SMP Thu May 15 18:06:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

IBus: version 1.5.0 is correctly installed and running as part of TT 14.04 (LTS). (iBus Daemon runs in current session)
Fonts: ipafont-gothic and ipafont-mincho are installed, as evidenced by a proper 'fc-list'
Japanese Anthy text entry: works well (direct trial), except in terminal window.
Chinese SunPinyin text entry: works well, except in terminal window, but not an acceptable option for this user
Chinese Pinyin: fails <-- ***

The whole gui seems to work perfectly well, setting of preferences, Eｎｇｌｉｓｈ full width text entry and toggling between English and Chinese Pinyin entry with the shift key.

Chinese Text entry (apparently) is well configured with my choice of "Chinese Pinyin". Pinyin entry actually works and iBus actually reacts well to "nihao", by proposing "你好" in return (this was pasted from a translation website, not generated by this iBus !) .
However selecting that choice with the space bar, results invariably in "[Invalid UTF-8]".
 (even after multpiple reboots & restarts of iBus)

Steps to reproduce the error:
  Unknown.
  This is the result of a normal dual boot install.
More info:
  If more info is required (hardware, etc), ask.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem with lubuntu 14.04 right after a fresh installation.

[Invalid UTF-8][Invalid UTF-8][Invalid UTF-8] :D

Ok. Please add your comment to launchpad if not already done and elevate
the number of point of this confirmed bug by one, for this bug to
receive more and faster attention from the dev platform. Thank you.

By the way, if Chinese is really needed, an alternative to Ibus is fcitx. It seems to work well. It seems pretty recent, before there wasn't any alternative.

我不喜欢iBus。:p
