I noticed another bug today, when you enable and disable the keyboard feature often then it is possible that the keyboard layout stucks in the US one. I got a N900 with a German QWERTZ keyboard and noticed that it get set to QWERTY when I enable the plugin. That is actually no big deal but it gets annoying when the keyboard stays as US one, disabling the app doesn't helps then. The only way to solve it is to set the keyboard to a different language and back to the original one again.
