Warning message always appears after adding some words

[efajk]

When I tried to add some words correctly, the waring message "Warning: chewing_userphrase_add( ) returns 0 ((null) :0)" always appears in command line. I think this warning message appears only when people doesn't type any word. I use ubuntu 15.10 64bits version I use following way to install chewing:

sudo apt-get install fcitx
sudo apt-get install im-config
sudo add-apt-repository ppa:fcitx-team/nightly
sudo apt-get install fcitx-chewing
im-config

It just works fine for me

When chewing_userphrase_add returns NULL(0), it means that adding phrase is failed. Maybe you just typed 一(chinese word) in bopomofo field, try ㄧ(real bopomofo) ref: #106 #108
