[CentOS] Crash when open a terminal after upgrading from centos5.9 to 5.11

Dear all, I had installed Centos 5.9 in my x86_64 system and I installed update yesterday. Just now after I initiated the system, I found it has been upgraded to centos 5.11. But the bad thing is now I cannot open a terminal. When I try to open a terminal, it just gives out a bug buddy window
