If a keyboard exists but it has no current focus, yet something asks the
input-panel to come up, we would crash here. Check that there is a focus
before attempting to use it.
Maybe there should not even exist a case where input-panel tries to come
up without a keyboard focus, but I am not sure there is no race where it
could happen.
In any case, this fix was brought up by the ivi-shell work, where I
suppose you can somehow hit it.
