I'm not able to provide a solution, just an explanation: You need to 
load the .elf file using the Insight debugger (or any other GDB 
frontend), because this file contains the required source code 
information for the debugger. Possibly your OpenOCD Configuration file 
is wrong, but not sure.

Also make sure, that compiler options  -O0 -gdwarf-2 are set. The 
current beta 4.3.99 contains a special Makefile.arm-gccdbg (Select 
arm-gccdbg as the Platform in the Configurator Settings).
