Sorry, I could have given more useful directions. What system are you
on? Are these errors preventing fcitx from starting up at all?

On Arch Linux I installed the "fcitx", "fcitx-libpinyin", and
"fcitx-googlepinyin" libraries -- the last two each have a dependency,
"libpinyin" and "libgooglepinyin", respectively. libpinyin and
libgooglepinyin are redundant with each other, as far as I can tell
either one should display the erroneous behavior, but you might have an
easier time installing one over the other.

There's also a "fcitx-configtool" which provides a GTK view on the
config files, that might be more work than it's worth.

On my machine the TriggerKey config is set in ~/.config/fcitx/config.
You might have to look around, but try to find the TriggerKey item. Once
fcitx is running, that's your hotkey for toggling input.

If fcitx won't start at all... I'm not sure how to debug that.
