Cannot choose the input method by clicking the icon after upgrading to lubuntu 16.04

[wtchen]

1. Originally I could choose the different input method (latin-letter or EN) by right clicking the icon on the sidebar, now the effect of right click and left click are the same (it will show the setting of gcin instead of the list of input method).

2. If you click the icon and choose "choose input method", you can still choose the input method, but notice the first icon "EN ctrl-alt-e" is missing.
