Description of problem:
When ibus-anthy starts up, it does not correctly load the romaji key table (ローマ字キーテーブル) settings from the ~/.gconf/desktop/ibus/engine/anthy/romaji_typing_rule/default/%gconf.xml file.
Settings made in the config dialog seem to be properly saved in the file, but when ibus-anthy is restarted, some romaji-kana mappings add by the user are lost.

Version-Release number of selected component (if applicable):
ibus-anthy-1.2.4-3.fc14.i686

How reproducible:
I tried the reproduce steps below three times and the bug was reproducible for all the times.

Steps to Reproduce:
1. Remove ~/.gconf/desktop/ibus/engine/anthy/romaji_typing_rule and log out from and log in to the gnome session. (ensure gconf is restarted)
2. Open ibus-anthy's config dialog and add the following two romaji-kana mappings:
  kwa -> くゎ
  kwi -> くぃ
3. Type "kwakwi" in a text editor and we get "くゎくぃ" correctly.
4. Restart ibus from the right-click menu of the ibus icon.
5. Type "kwakwi" in a text editor again and we get "くゎkうぃ" this time.
  
Additional info:
Note that "kwa" has the default mapping to "くぁ" while "kwi" has no default mapping. It seems that romajis without default mappings are not correctly loaded from the config file.
