Hello.
Recently, the guys from Google have to deal with an issue in Android Studio where the user can no longer type in the IDE. Their workaround is to restart ibus via "ibus restart", which works more or less [1]. As a side effect I noticed that wish and therefore gitk and git-gui die as soon as I execute the command. I want to let you know about this in case you can do anything about this.
Best, Tobias
