Problem description: 
This happens in Linux using the Ibus keyboard input with the IPA Unicode 5.1 (ver. 1.2) keyboard installed (available from www.sil.org)

When using the IPA Unicode Ibus input, the keystroke sequences do not generate the correct IPA (International Phonetic Alphabet) Unicode characters. Instead, only the first character in the keystroke sequence is displayed.

Other parts of my system are working correctly. For example, the keyboard input works fine with an ordinary text editor (gedit). Keyboard input also works fine when using the Ibus pinyin interface. However, a similar issue seems to exist typing into a browser window in Chrome, e.g. Google mail compose interface. I do not as yet know if the two issues are related.

Also, this is NOT a problem with the display; I can cut-and-paste the characters from a text document into LibreOffice, and they are displayed correctly. It is the keyboard input that is not functioning.

Steps to reproduce:
1. Open any LibreOffice document.
2. Change to IPA Unicode in the Ibus preferences, either using keyboard shortcuts or the Ibus UI.
3. Start typing. Example: type the following:
s=z=t=d=n>l=r=r>?=w=

Current behavior:
The following text is displayed:
sztdnlrr?w

Expected behavior:
the following text should be displayed:
ʃʒθðŋɬɹɾʔʍ

Platform (if different from the browser): 
Ubuntu 11.10 X86_64
              
Browser: Chrome/16.0.912.77
