The menu of the status icon offers no obvious way to get back to the initial state that shows the ibus icon. I have to go to an input field and type Ctrl-Space to achieve that. The corresponding scim menu has an "English" entry at the end of the list. It may be better to call it "No input method" or something similar (since the language may not actually be English)
Fixed in upstream. What for next release.
The new release has been built
