Please enable the verbose mode in the console -- there's a button in the
toolbar. This will tell exactly what the error is -- and I'm 51% sure
the problem is that you are trying to send MI command, and DSF thinks it's
CLI command, and sends something not right.

And this might be unrelated to whatever problem you are having in the first
place. CDI  debuggers have a way to enable verbose console mode in the
launch configuration. Please do that in DSF and then see if something
is wrong with any GDB response.
