Description:

It happended after I updated to gnome-shell 3.6.3.1
The kimpanel extension don't respose anymore randomly.
A screencast; http://www.tudou.com/programs/view/BVDw4j4yxaI/
Then I reload gnome-shell, and start Fcitx by command and it works again.
It occured more than twenty times in the past days.

A related talk here(in Chinese), maybe not related:
