Critical Dataloss! Text in input field of webpage will be cleared if Ibus-pinyin enabled

[suokunlong]

Simple steps to reproduce the problem:

1. Enable ibus-pinyin;

2. Go to this page: http://www.webodf.org/demo/ci/wodotexteditor-0.5.0-8-g471ccbe/localeditor.html
Then select some text
--> Result: the selected text will be deleted!
(this online app provided the ability to undo, so you are lucky to get your data back. But you wont be lucky when you are doing this on other websites!)

3. Go to this libreoffice bug reporting page: https://bugs.freedesktop.org/show_bug.cgi?id=mab4.2
Then click the "edit" link which locates on right side of " (mab4.2) LibreOffice 4.2 most annoying bugs".
(You need to login first)
--> Result: an empty input field shows up.
--> The expected result should be, an input field show up, with the original text in the field.
(Same result if you click the "Depends on" edit link. I first noticed this bug behaviour when I cleared all the bugs in the list while I was adding one bug to the list. I did not realize it until some told me that I cleared all the bugs!)

4. ... And many other web pages, I encounter the same issue. It only happens on ubuntu, not on Fedora 20, not on Windows!

All the above bug behaviour will not happen if you switch to "SunPinyin" instead.

When I first noticed this bug, I was thinking it may be a bug of firefox. But after further testing I find this not browser's issue. Today I finally get the reason: it's ibus-pinyin's bug!

Hope this be fixed soon. I can provide further information if needed.
Thanks!
