How reproducible:
If you log out gnome desktop, gnome-panel might crash. if you got the crash, run Abort to collect crash infomation then abort reports gdb has crashed.
After that I can reproduce without Abort.

Steps to Reproduce:
precondition:
You should have gnome-panel's coredump file.
1.Run gdb 
 gdb /usr/bin/gnome-panel
2.Run this command. 
 set debug-file-directory /usr/lib/debug:/var/cache/abrt-di/usr/lib/debug
3.Read corefile
 core-file /var/spool/abrt/ccpp-XXXXXXXXXX-XXXX/coredump
  
Actual results:
Read coredump file without crash.

Expected results:
gdb crashes.

Additional info:
I wrote simple program such as following c code. That code will crash and give coredump file to test gdb. When I run gdb and read corefile, gdb didn't crash.  

#include <string.h>

int main(int argc, char **argv)
{
	strcpy(NULL, argv[0]);
	return 0;
}
