--- Comment #66 from fujiwara tfujiwar@redhat.com --- (In reply to lnie from comment #65)
think it's caused by a special setting.Actually,what I really want to be fixed is: ibus crash after the reboot of a fresh installed system,and stay crashed. From #Comment48,49,one can know that many people saw this bug.
Comment 48 and 49 are the same backtrace(abort) but not your hang issue. After this abort will be closed fixed, I will ask to open another bug for your hang.
Did you reproduce your problem with Live KDE RC1?
