Comment 8 for bug 607095

I got same problem, but not only that. I am using 2 layouts, and suddenly the indicator hanged at single layout (Russian), and did not want to switch back to USA.

With this I was getting the keyboard input mixed all the time, i.e. the characters were taken randomly from either of the layouts. Running 'xev' showed that there is a constant flow of keyboard-related events which have no visible impact.
