Hi, I re-checked the log of my system. At last, I find there is an upgrade of scim (especially, scim-pinyin). After I downgrade all these scim packages, this problem is solved (1.4.2-1 to 1.4.1-1).
So, I believe this may be due to the new versions of scim packages. Sorry for this wrong bug report to gaim. Thank you very much. -- Hongzheng Wang
