I have problems with ibus. On some chinese input methods ibus vanishes from the control panel. Input method cannot be altered afterwards and I suppose ibus is more or less dead.
Regularly happens with the GooglePinyin input method.
At least, how can I restart ibus without rebooting.
can’t help with the ibus crash . . . but have you tried fcitx instead of ibus? It’s very stable in openSUSE and receives better support (as far as I can tell)
