Comment 13 for bug 335732

Calabacín, could you run
   /usr/lib/ibus/ibus-x11 &
to see if it makes any difference?

(if you have tcl/tk installed, you could run a quick test with
   echo {text,pack,focus}$' .t\n' | wish
)

I think it's a problem with the way ibus-daemon is launched (without -x flag).

Anyway, you'll find yourself stalled at the next handicap:
