Debugging in 1.4 RC1

I was wondering if anybody has ideas as to what needs to be changed either in 1.4RC1 or maybe that will have to be changed in the debuggers to work properly with the engine now.

the telnetDebugger doesn't work at all currently.. The ingame GUI version just says bogus errors: VRSN some other stuff, so I assume something in netcode has changed that is affecting the debugging
