yes, it failed as always. I've fould the problem has nothing to do with
gtkrc-2.0,

Have you tried a revdep-rebuild?  Did you recently change gcc

I don't use prelink.. , and even don't know what it is....
I compared all the open() system calls between outputs generated by root and
the normal user, and found something strange:  both root and the normal user
version trying to open libstdc++.so.6, after checking /etc/ld.so.conf, what
have made me confused is the root
version choose /usr/lib/libstdc++-v3/ thus the normal user choose
/usr/lib/gcc/i686-pc-linux-gnu/4.3.6/, probably this is the answer to the
crash, but I just wonder what make them having different choices with the
same ld.so.conf?


thank you..
