The gdb process exited unexpectedly (crashed) when I insert breakpoint

Hi
GDB crashes when I insert a breakpoint
With all projects.
Tried installing latest QT, without result.
use Fedora 12
Without a breakpoint I can pause and single step.

Debug Output:

dState changed from <unknown>(-1) to DebuggerNotReady(0).
