Installation and login worked. Contacts were synchronized as well as the chat history.
What does not
Typing Korean characters worked (I'm using Ubuntu 14.04 with the package ibus-hangul 1.4.2-3), but they show up as squares in the typing-field and are only recognizable in after being sent (or received).
Buttons did not appear in the windows, but windows can be closed using ALT + F4.
What was not tested
Audio calls, video calls, the whole range of emoticons.
