can't configure FCITX

trying to configure fcitx in leap 42.1
loading the configuration window as soon as I uncheck “only show current language” the config window immediately crashes and disappears showing a segmentation fault.


fcitx-configtool
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
Segmentation fault

I’m trying to configure Japanese input with mozc but it is impossible to do without unchecking “only show current language”.

Anybody have any idea?

Many thanks
