I cannot reproduce your problem.
Are you still able to see this backtrace?
Comment 11 Sanne Bregman 2013-01-01 20:53:30 UTC 
I've looked up and down this bug a few times, but I can't find my original message how/why this happened... So I'm afraid I can't reproduce this either. I have honestly no clue as to why this happened, sorry :(
Comment 12 Sanne Bregman 2013-01-01 20:55:39 UTC 
Oh wait! I already remember how/why this happened. This was due to a little issue with the Java game Minecraft in which dead keys weren't passed along properly. To "fix" this, ibus is killed, then Minecraft is started, and then ibus is restarted. Apparently the restarting of ibus failed once, but it turns out this isn't necessary anymore since one of the more recent versions of Minecraft. 

Now that I remember this, I tried to reproduce it but for some reason I can't.
