Mutiple users have confirmed that with scim 1.4.7, "FrontEnd/X11/Dynamic = true" completely fixes (works around) the lock-up issue.
So Wenzhuo, if you are still experiencing lock-up with "FrontEnd/X11/Dynamic = true" setting in up-to-date gutsy, please provide more information, such as which scim modules you have installed, how you started scim, etc.
