XKB+Ibus input methods?

[Martin Sourada]

Hi all,
after last batch of updates, "Czech (querty)" input method disappeared
from ibus. Some trivia:

I use mozc for Japanese, English (US), Russian (translit, m17n) and
Czech (qwerty) with ibus. It's inconvenient to manage half of them
via XKB (English and Czech) and the other by ibus (Japanese and Czech).
Since a long ago, Czech querty could have been used as ibus input method
without issues. That stopped somewhere around the time ibus config
dialogue got switched from gtk2 to gtk3. Thenceforth it offered only
Czech (which is qwertz, which I don't want) input method. I discovered
that if I added Czech (qwerty) to Settings->Keyboard Layout, ibus picked
it up and worked mostly as expected. This is no longer the case. Am I
seeing a bug or is there some other supported way to add XKBC keyboard
layouts to ibus in XFCE? Or am I supposed to use different input system
with XFCE (ibus seems to get more and more integrated with gnome)?

Any pointers?
