wish dies when ibus is restarted

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
