Ok i have downloaded all the debuginfo package on my RHEL6.2 server, and also i have to install with "--nodeps" options the package glibc-debuginfo-2.12-1.47.el6_2.12.x86_64.rpm because it require the glibc-debuginfo-common rpm package which do not found on Redhat website.

Here is now the result :
