Hi all:
This problem is very strange, so I can't promise that someone can reproduce it.
Sometimes when login (through gdm) to gnome I will find a "gdb.core" file in my home directory, but sometimes will not.
If I fond this "gdb.core" I can't "shut down" directly, if I hit "shut down", I will logout to gdm, but I can "shut down" the system from "gdm".
Seems, it's random. x(
OS information:
After the installation, I have been csup the system source code and ports tree, then I compiled the userland, the kernel, and every ports.
